Tribute to Daniel Duprez (1945 - 2022)
Born in 1945, Daniel Duprez obtained an Engineering Diploma from the Ecole Nationale des Industries Chimiques ENSIC (Nancy) in 1967. After joining the CNRS in 1969, Daniel Duprez obtained a Doctorate in Science (INPL Nancy) in 1975. His work focused on the conversion of aromatics on aluminas and on the study of the formation mechanisms of large aromatic molecules in coal. Following a two-year stay (1976-1978) in the "Catalysis" group of the Elf-Solaize research centre, he joined the catalysis laboratory in Poitiers in 1978.
It was during this period that he initiated the first work on the selective vaporisation of aromatics on metals. This work allowed him to develop the concept of surface mobility in catalysis. As the reaction rates are much more affected by the nature of the support than by the metal phase, he proposed a bifunctional metal/support mechanism in which the hydrocarbon is activated on the metal and the water on the hydrophilic sites of the support. To measure this mobility, he developed an 18O/16O exchange technique using the metal as a gateway for oxygen into the material. The experience acquired in the field of hydrocarbons was then applied to the steam reforming of alcohols and in particular ethanol for the production of hydrogen (fuel cells).
Since the 1990s, Daniel has also applied the concept of mobility to automotive pollution control catalysis, where the principle of "oxygen storage" in materials has proved decisive in accounting for the enhanced performance of ceria-based catalysts under transient oxygen concentration conditions. The tool developed in Poitiers has been adapted to the study of materials with very high oxygen mobility (ceria and especially mixed ceria-zirconia compounds), by introducing into the mobility model additional steps such as the formation of superoxide and peroxide species. More recently, and particularly since his emeritus in 2011, Daniel Duprez has focused on understanding the role of interfaces and grain boundaries (dislocations) in mobility and catalytic processes. His expertise, recognised worldwide from the United States to Japan, is reflected in more than 300 scientific publications, 20 reviews and book chapters and 78 invited conferences.
In parallel to his intense scientific activity, Daniel has played an important role in the development of heterogeneous catalysis in Poitiers as deputy director of the Laboratory of Catalysis in Organic Chemistry (LACCO) between 1991 and 1999 and then as director of LACCO for two terms, from 2000 to 2007. From 2008 to 2010, he directed the REAUMUR Federation which led to the creation of the Institute of Chemistry, Media and Materials of Poitiers (IC2MP).
Daniel Duprez has strongly contributed to the promotion of French catalysis at the international level, in particular through his role as President of the Catalysis Division of the Société Chimique de France from 2006 to 2010 and from 2011 to 2012.
Daniel Duprez has also worked hard to educate future generations in the fundamental principles and practice of catalysis. He has served the chemical community in a selfless way by organising or participating in the organisation of international symposia and conferences. He has taught the community through excellent and very important critical reviews on various aspects of catalysis. Throughout his career he has embodied the spirit of the teacher and the researcher, while making very important contributions to the application of catalysis in areas of great impact on sustainable chemical synthesis and the production of energy carriers for the future.
Emeritus research director from 2011 to 2021, Daniel has continued to come regularly to the IC2MP to exchange with his colleagues and pass on his knowledge, always with benevolence. Having left for Lyon a year ago for health reasons and to be closer to his children, he continued to keep in touch with each other both professionally and personally. His scientific curiosity was still very present and we will sadly miss his occasional sending of articles from scientific and non-scientific journals to discuss current events. All those who had the chance to collaborate with him will remember not only his scientific qualities, but also his many human qualities such as his generosity, his constructive spirit and his optimism.

Prof Geoff Bond 1927-2022 | Brunel University London
Written by Prof Bond's grandson, J. L. Bond, with contributions from Dr A. O. Taylor and other colleagues. Professor Geoffrey C Bond, PhD, DSc, FRSC, passed away after a short illness, peacefully in his sleep, on 9 January at Watford General Hospital, close to his home in Rickmansworth.
Dr. Kirill V. Kovtunov (1983 – 2020)
Our colleague and friend passed away at the age of only 37. Yet, he contributed substantially to the field that combines catalysis and magnetic resonance, including the development of NMR signal enhancement techniques for the mechanistic studies of catalytic reactions and operando NMR spectroscopy and imaging of reactors. In 2016, Kirill received the Young Scientist Prize at ICC16 in Beijing, China, and was invited to give a talk at ICC17 in San Diego. Through his research he developed strong ties with numerous collaboration partners in Russia and abroad. In December 2019, he defended his Habilitation thesis and was very enthusiastic about starting a number of new exciting projects. But life decided differently. In January Kirill was diagnosed with cancer, and despite his unwavering resolve and determination to fight the disease, we lost him. His demise is a tremendous grief for his family, colleagues, students and friends.

Professor Michel Che
Michel was born in Lyon in December 1941. After obtaining a degree in Chemical Engineering in Lyon, he joined the « Institut de Recherches sur la Catalyse », CNRS Laboratory (IRC) in Lyon. He was awarded his PhD in 1968 by the University of Lyon and subsequently was a postdoctoral fellow at Princeton University (1969–1971) working with Prof J. Turkevich. In 1975, he moved from the IRC to assume the role of professor at Université P. & M. Curie-Paris-6, where he became director of the « Laboratoire de Réactivité de Surface » and in 1995 he became senior member of the « Institut Universitaire de France ».
Michel Che was very active in serving the catalysis and wider scientific community. He was President of the « Catalysis Division » of the « Société Chimique de France » and from 2007-2009 he was Vice-President of « Société Chimique de France» . From 1993 – 1995, he was the President-Founder of EFCATS (the European Federation of Catalysis Societies) being instrumental in initiating the biennial EuropaCat congresses. He was also President of IACS (the International Association of Catalysis Societies) between the years 2000-2004.
He was the recipient of numerous international awards, most notably from China, France, Italy, Germany, Japan The Netherlands, Poland, the UK, the USA and he was a pro-active member of many scientific committees, and in particular in those in China, France, Japan and UK.
He pioneered a molecular approach to catalyst design by bridging the gap between homogeneous and heterogeneous catalysis through the new field of interfacial coordination chemistry based on the combined use of transition metal complexes, specific isotopes and physical techniques. He made a major contribution to the improved understanding of the elementary step occurring at the solid-liquid (gas) interface.
He had especially close ties with China where his father had been born before emigrating to France (Lyon). Indeed, Michel was one of the first foreign scientists who visited China as early as 1977, when China opened up once again to the world. Due to his great contributions to the scientific development of China, and in particular international cooperation between France and China, he was awarded the International Cooperation Award of China which was presented to him by the Chinese President and which is the highest Chinese honor for foreign scientists.
In addition to his significant scientific contributions, Michel was greatly appreciated by all for his human qualities. All his students recognised him as an outstanding mentor. As a chairman of many committees, he used his influence to great effect including by defining research strategies, by promoting international collaborations and by fostering and educating generations of young scientists to become active and leading scientists across the globe. As Sir John Meurig Thomas wrote to me « he was a noble human being and a so fine scientist ».
We shall always remember Michel’s contribution to catalysis and his friendship with great affection. His spririt and soul will remain in our hearts for ever.
