Professor Douglas Stephan- 2004 Ciapetta Lecturer

The 2004 F. G. Ciapetta Lectureship is awarded to Professor Douglas Stephan of the Department of Chemistry & Biochemistry, University of Windsor, Windsor, Ontario, Canada. The F.G. Ciapetta Lectureship in Catalysis is cosponsored by Davison Catalyst, a business unit of W. R. Grace & Co and The North American Catalysis Society. The award is given in recognition of substantial contributions to one or more areas in the field of catalysis with emphasis on industrially significant catalysts and catalytic processes and the discovery of new catalytic reactions and systems of potential industrial importance. The Award consists of a plaque, an honorarium and additional money is available to cover traveling expenses to visit the local clubs. Local clubs should contact Professor Stephan directly to make travel arrangements.

Professor Stephan received his Ph.D. in Inorganic Chemistry from the University of Western Ontario. He undertook a NATO Postdoctoral Fellow in Chemistry at Harvard University before moving to the University of Windsor where he has spent his career doing research. Doug Stephan’s research group has been active for over 20 years in studying the fundamental organometallic chemistry of early transition metals. He has received many distinctions and honors for his accumulated accomplishments during the course of his studies, but it was his recent success in developing a novel set of catalysts for polymerizing ethylene that have earned Doug Stephan many accolades both in industrial circles and among his academic peers. This development is expected to have a major impact on the Canadian petrochemicals industry, which is a significant part of the manufacturing capability in this country. Stephan’s innovative approach to ancillary ligand design quickly led to dramatic findings of new patentable catalysts that were highly active under industrial conditions. NOVA Chemicals’ goal of developing new single site catalyst technologies was significantly advanced with the discoveries of potential new catalyst compounds from the Stephan labs. In collaboration with a team of chemists and engineers at NOVA Chemicals Stephan’s team worked to explore and develop these new catalyst families towards commercialization. Stephan and his group have continued to study the structure-reactivity relationship of these single-site catalysts. In addition, Stephan’s group has discovered and studied a number of unusual deactivation pathways that these new catalysts exhibit allowing optimization of process conditions. More recently, Stephan’s group has been studying modified systems that exhibit living catalyst behavior and their use in the formation of co- and block polymers. His new efforts are focused on developing new co-catalysts as well as strategies to late transition metal catalysts.

Alex Bell awarded 2003 Robert Burwell Lectureship in Catalysis

Professor Alexis T. Bell has been awarded the 2003 Robert Burwell Lectureship in Catalysis by the North American Catalysis Society. The Lectureship is sponsored by Johnson Matthey PLC’s Catalysts and Chemicals Division and is given in recognition of substantial contributions to one or more areas in the field of catalysis with emphasis on discovery and understanding of catalytic phenomena, catalytic reaction mechanisms and identification and description of catalytic sites and species. His research activities have led to more than 400 publications in the most prestigious journals in catalysis, chemistry and chemical engineering. Over many years he has applied cutting-edge spectroscopy and theory to study surfaces before and after catalytic reactions.

His nominators offered some of the following remarks. His earlier work with Professor Doros Theodorou pioneered the application of statistical mechanics and molecular dynamics for predicting the adsorption and diffusion of molecules in zeolites. This represented one of the first quantitative applications of theoretical methods to systems of direct catalytic relevance. Later his work with Professor Arup Chakraborty succeeded in using quantum mechanical calculations to determine the siting and stability of metal cations exchanged into zeolites. In the area of Fischer-Tropsch synthesis, his elegant use of in situ infrared methods, surface science techniques, and isotopic switch methods led to a mechanistic picture of “unprecedented clarity and relevance.” Rate constants for elementary steps and the identity and reactivity of specific adsorbed intermediates were measured and ultimately used to elucidate the underlying structure-function relations for chain growth as well as the operative basis for widely reported strong meta-supported interactions. His studies have led to demonstration of a novel bifunctional mechanism for methanol synthesis and leads to strong effects of Lewis acidity and basicity of ZrO2 on activity and selectivity. He has also made significant contributions in the area of zeolite catalysis by elucidating the mechanism of both the synthesis and function of these heterogeneous catalysts.

Together with Professor Clay Radke, the application of NMR methods led to the direct observation of the structure-directing role of organic and inorganic cations during synthesis and to a clear mechanistic picture of their self-assembly in complex solutions and gels. A combination of kinetic, infrared, isotopic and theoretical studies also led to a clearer mechanistic and structural picture of the nature of exchanged cations in zeolites and their involvement in forming and stabilizing reactive intermediates in the reduction of NO by hydrocarbons. In the area of metal oxides, Alex pioneered the use of Raman spectroscopy for the structural characterization of dispersed structures. His applications of these methods to the characterization of oxidative dehydrogenation catalysts led to specific assignments of site reactivity and to a comprehensive picture of the mechanism and site requirements for desired and undesired reactions of alkanes on dispersed oxides. More recently, working in collaboration with Professor Enrique Iglesia, he has also explored the use of in situ UV-visible and X-ray absorption spectroscopy in measuring the number of active sites and reduced centers during alkane oxidation reactions. Throughout all this work, Alex has repeatedly demonstrated a natural talent that allows him to translate his research on catalytic phenomena, catalytic reaction mechanisms, and the identification and description of catalytic sites for a wide range of chemistries into understandable terms for his audience.

The lectureship comes with an honorarium and travel stipend that will allow him to visit many of the local clubs of the North American Catalysis Society in order to stimulate both young and old minds to the marvels of catalysis.

Houdry Award to Avelino Corma

The 2003 Eugene J. Houdry Award in Applied Catalysis to Professor Avelino Corma Canos of the Technical University of Valencia, Spain. The award is sponsored by Süd-Chemie, Inc. The purpose of the Award is to recognize and encourage individual contributions in the field of catalysis with emphasis on the development of new and improved catalysts and processes representing outstanding advances in their useful application.

Professor Corma is widely recognized as a prolific and versatile contributor to the science and technology of heterogeneous catalysis. In particular, he has participated in the discovery of new catalysts for the isomerization of light, straight-run naphtha now in commercial use, others for bottoms upgrading in FCC units, a catalyst for a commercial process for the selective epoxidation of propylene, the development of weakly basic solid catalysts for selective isomerization of alpha olefins, and the commercialization of catalysts for the isomerization of beta pinene. His nominators commented: a set of catalyst compositions disclosed in a patent for the isomerization of light, straight-run naphtha (US #5,057,471) is in current use in ten commercial units. These catalysts are based on H-mordenite materials with very low aluminum content and they show unprecedented sulfur resistance. His group is also credited with the discovery and use of Al-containing sepiolite materials as additives for bottoms upgrading in FCC units. Following successful scale-up activities, these catalysts are in current use in at least one FCC refinery unit.

A collaboration between the Corma group and Sumitomo Corporation has led to a commercial process for the selective epoxidation of propylene to propylene oxide using cumene hydroperoxide. The use of a zeolitic material with large pores and a Si-O-Ti framework leads to unprecedented selectivity and stability. A commercial reactor using this technology is currently in start-up in Japan.

A joint project with Tagasako Corporation and Acedesa led to the commercialization of heterogeneous catalysts for the isomerization of beta pinene to alpha pinene, as part of an overall process for the synthesis of a family of sandalwood-type fragrances.
Professor Corma’s group has also pioneered the use of automated micro-activity test units, whose design was patented and licensed, and about 30 of these units have been placed in service.

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.
