Emmett Award to Francisco Zaera

The Paul H. Emmett Award in Fundamental Catalysis to Professor Francisco Zaera of the University of California at Riverside, USA. The award is sponsored by the Davison Chemical Division of W.R. Grace and Company. The Award is intended to recognize and encourage individual contributions (under the age of 45) in the field of catalysis with emphasis on discovery and understanding of catalytic phenomena, proposal of catalytic reaction mechanisms and identification of and description of catalytic sites and species.

Professor Zaera’s main interests lie with the study of mechanisms of surface reactions by using modern surface-sensitive techniques. He is noted for bridging the knowledge on surface reactions with that of organometallic systems and for his extension of kinetic theories to reactions on surfaces. His nominators commented that he has placed particular emphasis on making a connection between the atomic details of surface reactions and heterogeneous catalytic processes. While most surface kinetic concepts have been recognized for some time, Francisco is credited with quantifying the kinetic consequences of these effects by a variety of surface science techniques to rationalize the rates observed in model systems and correlate them with practical heterogeneous catalysis rates.

He has been given credit for unequivocally establishing that most hydrocarbon processing catalysts are covered with a carbonaceous layer during the catalytic process. By performing isotope labeling experiments and using vibrational spectroscopy and molecular beam studies, Professor Zaera determined that those deposits are not direct intermediates in hydrogenation-dehydrogenation steps, but rather an play an indirect role by tempering the high activity of the metal surfaces and providing a reservoir for the surface hydrogen. He is also credited with establishing the prominence of hydride and reductive elimination steps as the main conversion pathways for alkyl fragments on transition metals. He has also shown how specific small changes in relative rates among competing reactions can account for vast differences in selectivity observed among some Group VIII metal centers.

Israel Wachs receives 2001 Clean Air Excellence Award

Professor Israel Wachs of Lehigh University’s Chemical Engineering Department has received a 2001 Clean Air Excellence Award. The EPA 2001 Clean Air Excellence Awards program honors outstanding, innovative efforts that help to make progress in achieving cleaner air. The research, sponsored by Georgia-Pacific Corp., has provided the pulp industry with a potentially profitable and innovative third alternative method of processing their waste gases. Using a new process and catalyst developed at Lehigh, the methyl alcohol and mercaptans can be converted to formaldehyde, a building-block chemical used for the adhesives, which find application in the plywood industry. [See www.pollutionengineering.com or N. Moretti’s article in Pollution Engineering, Jan. 2002, pp 24-28]. The waste gases are simply processed through a plant, which is similar in design to a conventional formaldehyde plant that utilizes commercial-grade methyl alcohol as a feed material. The novel environmentally benign process was conceptually developed and experimentally proven on a laboratory scale (see US Patent Nos. 5,907,066 and 6,198,005 B1 to I.E. Wachs/Lehigh University). The pilot plant studies were performed at Georgia-Pacific’s Brunswick, GA pulp mill on the real industrial waste streams.

The Clean Air Excellence Awards [http://www.epa.gov/oar/caaac/program.html] Program, sponsored by the U.S. Environmental Protection Agency’s (EPA’s) Office of Air and Radiation, was established in 2000 at the recommendation of the Clean Air Act Advisory Committee (CAAAC). The CAAAC is a policy-level advisory group to the EPA. The Awards Program annually recognizes and honors outstanding, innovative efforts that help to make progress in achieving cleaner air.

The award criteria are: (1) the technology is commercially viable and can be widely applied, (2) the technology is cost-effective relative to other air pollution technologies that already exist and (3) the technology is developed at the prototype stage or beyond. In 2000, XononTM Cool Combustion System – Catalytica Combustion Systems, Inc. received an award for developing the XononTM Cool Combustion system to reduce nitrogen oxides by 90 percent. XononTM prevents the formation of nitrogen oxides before they can form and has been applied in Santa Clara, California in an industrial gas turbine.

Catalysis is focus of 2001 Nobel Prize in Chemistry

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize
in Chemistry for 2001 for the development of catalytic asymmetric synthesis, with one half jointly to:

William S. Knowles (St Louis, Missouri, USA) and Ryoji Noyori (Nagoya University, Chikusa, Nagoya, Japan) “for their work on chirally catalysed hydrogenation reactions” and the other half to K. Barry Sharpless (the Scripps Research Institute, La Jolla, California, USA) “for his work on chirally catalysed oxidation reactions”.

Mirror Image Catalysis

Many molecules appear in two forms that mirror each other – just as our hands mirror each other. Such molecules are called chiral. In nature one of these forms is often dominant, so in our cells one of these mirror images of a molecule fits “like a glove”, in contrast to the other one which may even be harmful. Pharmaceutical products often consist of chiral molecules, and the difference between the two forms can be a matter of life and death – as was the case, for example, in the thalidomide disaster in the 1960s. That is why it is vital to be able to produce the two chiral forms separately.

This year’s Nobel Laureates in Chemistry have developed molecules that can catalyse important reactions so that only one of the two mirror image forms is produced. The catalyst molecule, which itself is chiral, speeds up the reaction without being consumed. Just one of these molecules can produce millions of molecules of the desired mirror image form.

William S. Knowles discovered that it was possible to use transition metals to make chiral catalysts for an important type of reaction called hydrogenation, thereby obtaining the desired mirror image form as the final product. His research quickly led to an industrial process for the production of the L-DOPA drug which is used in the treatment of Parkinson’s disease. Ryoji Noyori has led the further development of this process to today’s general chiral catalysts for hydrogenation.

K. Barry Sharpless, on the other hand, is awarded half of the Prize for developing chiral catalysts for another important type of reaction – oxidation.

The Laureates have opened up a completely new field of research in which it is possible to synthesise molecules and material with new properties. Today the results of their basic research are being used in a number of industrial syntheses of pharmaceutical products such as antibiotics, anti-inflammatory drugs and heart medicines.

Manos Mavrikakis selected for the 2009 Paul H. Emmett Award in Fundamental Catalysis

I am pleased to announce that Professor Manos Mavrikakis has been selected for the 2009 Paul H. Emmett Award in Fundamental Catalysis. The award consists of a plaque and a prize. The purpose of the Award is to recognize and encourage individual contributions (under the age of 46) in the field of catalysis with emphasis on discovery and understanding of catalytic phenomena, proposal of catalytic reaction mechanisms and identification of and description of catalytic sites and species.

Since 1999 Manos has been with the Department of Chemical & Biological Engineering, University of Wisconsin – Madison. Manos is one of the world leaders in the area of computational chemistry in catalysis. He has also served as Visiting Professor, Department of Chemical Engineering, Technical University of Denmark, Lyngby, Denmark. The primary research focus of Manos’ group is the fundamental understanding of surface reactivity, using state-of-the-art first-principles methods, and extensively collaborating with experimental experts. Manos has coauthored more than 80 original publications. He is a member of the editorial board of Surface Science and of the Annual Review of Chemical & Biomolecular Engineering. Dr. Mavrikakis has pioneered the use of Density Functional Theory (DFT) methods in the screening of pure and alloy metal catalysts to discover which metals or alloys have potential to yield catalysts of improved activity and/or selectivity. Manos has been unique in having used theoretical methods to find new, interesting classes of systems and site-nanostructures. Key to his success here was the use of fundamental principles concerning the relationships between the energetics of certain key intermediates and the activation barriers for the rate-controlling steps to make this screening procedure faster.

In particular, Manos demonstrated that possibility by identifying bimetallic alloys which bind atomic H as weakly as the noble metals (Cu, Au), but are able to break the H-H bond in H2 more easily than noble metals. Such Near-Surface-Alloy (NSA) materials are ideal for low temperature, highly selective, H-transfer reactions (e.g., in pharmaceutical production), and energy related catalytic applications. Also, Manos’s group systematically studied Oxygen Reduction Reaction (ORR) on a number of late transition metals, including bimetallic and ternary alloys of Pt. The result of that work was the construction of stable, ternary NSAs, which contain much less Pt, and are up to a factor of four more active than pure Pt ORR electrocatalysts. Manos also has discovered many interesting aspects of catalytic reaction mechanisms that have inspired the field. In particular, very recently Manos’ group has proposed a novel low-temperature reaction mechanism for the preferential oxidation of CO in the presence of H2, which explains the room-temperature reactivity of Ru-Pt core-shell nanoparticles. The specific nanoparticles were identified by Manos’ group from first-principles as very active and selective PROX catalysts, and those predictions were confirmed upon synthesis and catalytic testing of the Ru-core Pt-shell nanoparticles. Manos also followed up his detailed gas-phase methanol decomposition DFT work with experiments and microkinetic modeling, to show that one can accurately predict experimental reaction rates directly from first principles. In the area of water gas shift catalysis, his efforts have led to a completely new water-gas shift reaction mechanism involving carboxyl species on Cu, Pt, and Au surfaces, which is quite general and may be applicable to other low temperature water-gas shift catalysts. Importantly, this mechanism is shown to be operational under realistic industrial water-gas shift conditions.

Manos will give a plenary lecture and be recognized at the 2009 North American Catalysis Society meeting in San Francisco.
