In Memoriam: Juan F. Garcia de la Banda (1921–2015)

Juan_F_Garcia_de_la_BandaJuan Fran­cis­co Gar­cía de la Ban­da was born in Madrid (Spain) in 1921. He stud­ied Chem­istry and Math­e­mat­ics in the Uni­ver­si­ties of Val­ladol­id, Oviedo and Madrid, com­plet­ing his Bach­e­lor Degree in 1943. In 1948 he pre­sent­ed his PhD dis­ser­ta­tion (“Rela­tion between calorif­ic con­duc­tiv­i­ty and vapor pres­sure of high boil­ing point sub­stances”) super­vised by Pro­fes­sors Foz-Gazul­la and Colom­i­na and car­ried out at the Insti­tu­to de Quími­ca Físi­ca “Roca­solano” (IQFR) of the Span­ish Coun­cil for Sci­en­tif­ic Research (CSIC).

He stud­ied in Bris­tol between 1951 and 1952 with Pro­fes­sor William E. Gar­ner with Dr. Den­nis A. Dow­den at the Catal­y­sis Group at ICI. After­wards, he returned to Spain, with­in the frame­work of the IQFR and found­ed the “Lab­o­ra­to­ry on Catal­y­sis”, which became the birth­place of the Insti­tu­to de Catáli­sis y Petroleo­quími­ca (ICP) in 1975. He was the first Direc­tor of the ICP and the indi­vid­ual most respon­si­ble for enhanc­ing the scope and qual­i­ty of research in catal­y­sis and bio­catal­y­sis in Spain.

He par­tic­i­pat­ed in the First Inter­na­tion­al Con­fer­ence on Catal­y­sis (ICC) held in Philadel­phia in 1956 and main­tained per­son­al and pro­fes­sion­al links with many U.S. catal­y­sis researchers, espe­cial­ly through his per­son­al friend­ship with Dr. Heinz Heine­mann through­out their careers. He pro­posed and orga­nized the 1st Iberoamer­i­can Sym­po­sium on Catal­y­sis, held in Madrid in 1968, the first in a series that will cel­e­brate its 25th edi­tion this year in Mon­te­v­ideo.

Pro­fes­sor Gar­cia de la Ban­da served in sev­er­al influ­en­tial posi­tions with­in the research and devel­op­ment and sci­en­tif­ic struc­ture at the high­est lev­els in the gov­ern­ment of Spain. He is with­out doubt the most influ­en­tial and impact­ful pro­mot­er of catal­y­sis research in Spain in the 20th cen­tu­ry and the key indi­vid­ual in the for­ma­tive years of the catal­y­sis com­mu­ni­ty in Spain.
His pres­ence and his sage advice will be missed.

In Memoriam: John T. Yates, Jr. (1935–2015)

John_YatesPro­fes­sor John T. Yates, Jr. received his B.S. degree from Juni­a­ta Col­lege and his Ph.D. in phys­i­cal chem­istry from M.I.T. After three years as Assis­tant Pro­fes­sor at Anti­och Col­lege, he joined the Nation­al Bureau of Stan­dards, first as a NRC Post­doc­tor­al Research Fel­low and then as a mem­ber of its sci­en­tif­ic staff. His research in the fields of sur­face chem­istry and physics, includ­ing both the struc­ture and spec­troscopy of sur­face species, the dynam­ics of sur­face process­es, and the devel­op­ment of new meth­ods for research in sur­face chem­istry, kept him at the fore­front of this field of sci­ence through­out his long and dis­tin­guished career.

Pro­fes­sor Yates joined the Uni­ver­si­ty of Pitts­burgh in 1982 as the first R.K. Mel­lon Pro­fes­sor of Chem­istry and as Found­ing Direc­tor of the Uni­ver­si­ty of Pitts­burgh Sur­face Sci­ence Cen­ter. He estab­lished and led the Sur­face Sci­ence Cen­ter and men­tored 40 Ph.D stu­dents and more than 100 senior researchers at Pitts­burgh. He moved to the Uni­ver­si­ty of Vir­ginia in 2006 as a Pro­fes­sor and Shan­non Research Fel­low; there, he estab­lished a new research pro­gram in Sur­face Sci­ence and became active in the new field of astro­chem­istry.

Pro­fes­sor Yates served as Asso­ciate Edi­tor of Chem­i­cal Reviews and of ACS Lang­muir and on the Advi­so­ry Boards of Chem­i­cal & Engi­neer­ing News and Chem­istry World. He was active as a mem­ber of the AVS Boards of Direc­tors and Trustees and as Chair of the AVS Sur­face Sci­ence Divi­sion, the APS Divi­sion of Chem­i­cal Physics, and the ACS Divi­sion of Col­loid and Sur­face Chem­istry. He chaired three Gor­don Research Con­fer­ences.

He was the recip­i­ent of the AVS Medard Welch Award, the ACS Arthur W. Adam­son Award for Dis­tin­guished Ser­vice in the Advance­ment of Sur­face Chem­istry, the ACS Peter Debye Award in Phys­i­cal Chem­istry, and an Alexan­der von Hum­boldt Senior Research Award. He was elect­ed to the Nation­al Acad­e­my of Sci­ences in 1996. Dur­ing his dis­tin­guished career, he co-authored more than 700 arti­cles in the lead­ing jour­nals of chem­istry and physics.

We mourn his pass­ing as we cel­e­brate his achieve­ments.

In Memoriam: Theodore A. Koch (1925 – 2014)

Theodore KochDr. Theodore A. Koch, 88, a retired DuPont research sci­en­tist passed away peace­ful­ly at his home in Wilm­ing­ton, Delaware on Sep­tem­ber 13, 2014.

A native of upstate New York, Koch stud­ied chem­istry at St. Michael’s Col­lege in Burling­ton, VT and the Uni­ver­si­ty of Penn­syl­va­nia in Philadel­phia, PA, earn­ing his Ph.D. in chem­istry in 1952. He joined the DuPont Co. ulti­mate­ly retir­ing from its Nylon busi­ness unit as a DuPont Fel­low after 48 years of ser­vice. An author­i­ty on het­ero­ge­neous cat­a­lysts, Koch spent his entire career devel­op­ing chem­i­cal process­es and bring­ing them from the bench­top to com­mer­cial­iza­tion with marked cre­ativ­i­ty and tenac­i­ty.

Notable tech­ni­cal accom­plish­ments in Koch’s career includ­ed devel­op­ing a new cat­a­lyst for nitrous oxide destruc­tion (an ozone-deple­tion byprod­uct from Nylon man­u­fac­ture), devel­op­ment of a new process for hydro­gen cyanide man­u­fac­ture and improve­ments to many poly­mer inter­me­di­ates process­es. Koch received the award for Excel­lence in Cat­alyt­ic Sci­ence and Tech­nol­o­gy from the Catal­y­sis Club of Philadel­phia in 1994 and the Lavoisi­er Medal for Tech­ni­cal Excel­lence from the DuPont Co. in 1998. His exter­nal roles includ­ed adjunct Pro­fes­sor of Chem­i­cal Engi­neer­ing at the Uni­ver­si­ty of Delaware; pres­i­dent of the Catal­y­sis Club of Philadel­phia; and mem­ber­ship in the North Amer­i­can Catal­y­sis Soci­ety, the Amer­i­can Insti­tute of Chem­i­cal Engi­neers, the Organ­ic Reac­tions Catal­y­sis Soci­ety, and the Amer­i­can Chem­i­cal Soci­ety. He held 29 patents and co-authored 18 jour­nal arti­cles and one text­book on catal­y­sis enti­tled, “Cat­a­lyst Man­u­fac­ture.”

Koch is sur­vived by his wife of 62 years, Anne, his five chil­dren, five grand­chil­dren and extend­ed fam­i­ly. His mem­o­ry lives on through the Theodore A. Koch Fund that will rec­og­nize and reward Delaware Val­ley achieve­ments in catal­y­sis research. Char­i­ta­ble dona­tions may be made to the Catal­y­sis Club of Philadel­phia, Ted Koch Fund, c/o Stephen Har­ris, Trea­sur­er, Ren­matix, 660 Allen­dale Road, King of Prus­sia, PA 19406.

In Memoriam: Helmut Knözinger (1935–2014)

KnoezingerHel­mut Knözinger passed away at his home in Munich on Jan­u­ary 12, 2014, at age 78. The catal­y­sis com­mu­ni­ty los­es an active mem­ber of many years, a con­trib­u­tor of out­stand­ing sci­ence, leader in var­i­ous orga­ni­za­tions, edi­tor of key pub­li­ca­tions, and part­ner in vibrant col­lab­o­ra­tions.

Knözinger stud­ied Physics at Lud­wig-Max­i­m­il­ians-Uni­ver­sität München, with Phys­i­cal Chem­istry becom­ing his area of empha­sis dur­ing his time as a doc­tor­al stu­dent. His dis­ser­ta­tion (1961), which was super­vised by Georg-Maria Schwab, was his entrance into the field of catal­y­sis; he inves­ti­gat­ed the suit­abil­i­ty of the cat­alyt­ic decom­po­si­tion of methyl for­mate as a test reac­tion. He con­tin­ued on with the Habil­i­ta­tion (1967), the qual­i­fi­ca­tion for pro­fes­sor­ship with­in the Ger­man aca­d­e­m­ic sys­tem (Doc­tor of Sci­ences in oth­ers). The top­ic of the asso­ci­at­ed the­sis was the dehy­dra­tion of ethanol on alu­mi­na, a mate­r­i­al that would lat­er be the sub­ject of his per­haps most famous arti­cle. Knözinger held var­i­ous aca­d­e­m­ic posi­tions at Lud­wig-Max­i­m­il­ians-Uni­ver­sität München, with an inter­lude as a guest pro­fes­sor at the Uni­ver­si­dad Cen­tral de Cara­cas, Venezuela (1968/69), before he arrived at his final rank of pro­fes­sor (1980). He remained true to his alma mater until his offi­cial retire­ment in 2000, after which he kept an office and con­tin­ued to be active as a researcher and edi­tor.

Knözinger researched in many dif­fer­ent areas of catal­y­sis and excelled at devel­op­ing and apply­ing spec­tro­scop­ic meth­ods for the char­ac­ter­i­za­tion of cat­a­lysts. Each of the class­es of mate­ri­als in his focus can be asso­ci­at­ed with meth­ods that he tai­lored for the pur­pose of their inves­ti­ga­tion. He made sig­nif­i­cant con­tri­bu­tions to the char­ac­ter­i­za­tion of acid-base prop­er­ties of oxid­ic mate­ri­als, ana­lyz­ing the OH groups spec­tro­scop­i­cal­ly, and exten­sive­ly using car­bon monox­ide (CO) as a probe but also explor­ing much sought-for probe mol­e­cules for basic sur­face prop­er­ties. This work is doc­u­ment­ed in many orig­i­nal and review arti­cles, includ­ing those on alu­mi­na in Catal­y­sis Reviews-Sci­ence and Engi­neer­ing in (with Rat­nasamy, 1978), on CO adsorp­tion in Mate­ri­als Chem­istry and Physics (with Zaki, 1987), on weak­ly inter­act­ing probes for zeo­lites in Jour­nal of the Chem­i­cal Soci­ety — Fara­day Trans­ac­tions (with Huber, 1998), and on acid-base char­ac­ter­i­za­tion in the Hand­book of Het­ero­ge­neous Catal­y­sis (2008). Relat­ing to his work on CO as a probe mol­e­cule, he also applied his skill in infrared spec­troscopy to sup­port­ed car­bonyl com­plex­es, of which he wrote in Ange­wandte Chemie Inter­na­tion­al Edi­tion (with Lamb and Gates, 1988). Oxides sup­port­ed on oth­er oxides was anoth­er focus area, with appli­ca­tions of the cat­a­lysts for exam­ple in hydrodesul­fu­r­iza­tion and selec­tive cat­alyt­ic reduc­tion. In addi­tion to probe mol­e­cule adsorp­tion and IR spec­troscopy — his forte, he applied Raman, UV-vis, and pho­to­elec­tron spec­troscopy. To inves­ti­gate the mech­a­nism of dis­per­sion of oxides on oth­er oxides, exper­i­ments to observe the trans­port were designed, and in a long-last­ing col­lab­o­ra­tion with the Insti­tute for Plas­ma Physics in Garch­ing (a Max-Planck Insti­tute), thin film mod­el cat­a­lysts were inves­ti­gat­ed by sur­face sci­ence tech­niques such as ion scat­ter­ing and Auger elec­tron spec­troscopy. Exam­ples of this work are the arti­cles on molyb­de­na sup­port­ed on alu­mi­na in Jour­nal of Phys­i­cal Chem­istry (with Jeziorows­ki, 1978) or on sol­id-sol­id wet­ting in Sur­face Sci­ence in (with Leyr­er, Mar­graf, and Taglauer, 1988).

Knözinger’s work was rec­og­nized with nation­al and inter­na­tion­al awards, among them the Cia­pet­ta Lec­ture­ship (1980), the Ipati­eff Lec­ture­ship (1988), the Max-Planck Research Award (1995), the Prix Gay Lus­sac Hum­boldt Prize (1997), and the Alwin Mit­tasch Medal of Dechema (1998). He became an hon­orary mem­ber of the Hun­gar­i­an Acad­e­my of Sci­ences in (1995), a mem­ber of the Acad­e­mia Europaea (2000), and an hon­orary pro­fes­sor of Nankai Uni­ver­si­ty, Tian­jin, Chi­na (2004). He was a mem­ber of chem­i­cal and catal­y­sis soci­eties, and helped orga­nize nation­al and inter­na­tion­al con­fer­ences on catal­y­sis. Notably, he was first a mem­ber of the Euro­pean Asso­ci­a­tion of Catal­y­sis and then lat­er the rep­re­sen­ta­tive of the Fed­er­al Repub­lic of Ger­many in the Coun­cil of the Euro­pean Fed­er­a­tion of Catal­y­sis Soci­eties (1993–1999). He also act­ed as pres­i­dent of the Inter­na­tion­al Asso­ci­a­tion of Catal­y­sis Soci­eties (1996–2000).

As edi­tor, Knözinger moved into the foot­steps of Schwab, who had edit­ed a hand­book of catal­y­sis. Togeth­er with Ertl and Weitkamp, Knözinger pub­lished the first edi­tion of the Hand­book of Het­ero­ge­neous Catal­y­sis with five vol­umes in 1997. Such was the suc­cess that a sec­ond edi­tion, with Schüth as addi­tion­al edi­tor and eight vol­umes, appeared in 2008. He served as an edi­tor of Advances in Catal­y­sis, in the years 1998 through 2011; under his reign, three vol­umes were ded­i­cat­ed to spec­tro­scop­ic analy­sis of the work­ing cat­a­lyst.

While Knözinger remained root­ed in Munich through­out his career, he cul­ti­vat­ed col­lab­o­ra­tions and exchange. He him­self was an avid trav­el­er and also a guest pro­fes­sor mul­ti­ple times, in Cara­cas, Xian­men, Evanston, Ams­ter­dam, and Paris. Researchers from around the world vis­it­ed his lab­o­ra­to­ry (their prove­nience was, in fact, tracked by pins in a wall map at the insti­tute), most­ly to per­form IR spec­tro­scop­ic exper­i­ments using his spe­cial­ly designed appa­ra­tus. Guests were treat­ed with gra­cious­ness and enjoyed Bavar­i­an hos­pi­tal­i­ty.

His con­stant inter­est in everybody’s research was man­i­fest in his dai­ly after­noon rounds through the labs with indi­vid­ual con­ver­sa­tions, his recep­tion of a knock at his office door, his overnight read­ing of man­u­scripts hand­ed to him. His reli­a­bil­i­ty and his self-dis­ci­pline were exem­plary. His advis­ing was nev­er force­ful, pro­mot­ing aca­d­e­m­ic free­dom and inde­pen­dence. A sig­nif­i­cant num­ber of stu­dents achieved the doc­tor­al degree under his guid­ance and are tes­ta­ment to his skill as an advi­sor and men­tor. Knözinger was a gift­ed ath­lete in his youth and a moun­tain enthu­si­ast; he insti­gat­ed reg­u­lar group out­ings – hik­ing in sum­mer and ski­ing in win­ter. He cre­at­ed an atmos­phere of togeth­er­ness that let team spir­it and humor flour­ish and friend­ships be forged.

Knözinger was also a tal­ent­ed pho­tog­ra­ph­er and adhered to this pas­sion through­out his life – his cam­era accom­pa­nied him on most occa­sions. The var­i­ous pho­tographs dis­played in his office spoke of his skill, of his trav­els around the world, and his eye as an observ­er.

Hel­mut Knözinger’s pres­ence and his views will be missed.

In Memoriam: George Donald Blyholder (1931–2013)

Blyholder - BWGeorge Don­ald Bly­hold­er was born Jan­u­ary 10, 1931 in Eliz­a­beth, New Jer­sey but he grew up in Kansas City, Kansas and Chica­go, Illi­nois. He received his BA from Val­paraiso U., his BS from Pur­due U. in chem­i­cal engi­neer­ing and a Ph.D. in chem­istry from the Uni­ver­si­ty of Utah. His the­sis was enti­tled “Kinet­ics of Graphite Oxi­da­tion” and a part of this was pub­lished with his advi­sor, the renowned kinetist Hen­ry Ery­ing. While a grad­u­ate stu­dent, he met and mar­ried Bet­ty Sue Con­rad. Fol­low­ing grad­u­a­tion, he did post­doc­tor­al stud­ies at the Uni­ver­si­ty of Min­neso­ta and then at The Johns Hop­kins Uni­ver­si­ty with Prof. Paul H. Emmett. His work with Emmett involved the use of C‑14 labeled ketene to study the Fis­ch­er-Trop­sch reac­tion mech­a­nism. In 1959, he moved to Fayet­teville, Arkansas as a pro­fes­sor of chem­istry at the Uni­ver­si­ty of Arkansas. There he was involved in pio­neer­ing research on the use of infrared spec­troscopy to study catal­y­sis. His pub­li­ca­tion “Mol­e­c­u­lar orbital view of chemisorbed car­bon monox­ide” in the Jour­nal of Phys­i­cal Chem­istry in 1964 has become a clas­sic pub­li­ca­tion with 719 cita­tions and prob­a­bly more where it is just referred to as the “Bly­hold­er Mod­el”. He retired in 1996, becom­ing an emer­i­tus pro­fes­sor. He pub­lished more than 100 arti­cles in sci­en­tif­ic jour­nals with most in the area of sur­face sci­ence. His death at age 82 was on Febu­rary 24, 2013.
