Bert Weckhuysen, a Distinguished University Professor at Utrecht University (The Netherlands), received his Master and PhD degrees from Leuven University (Belgium) in 1991 and 1995. He has worked as a postdoctoral fellow at Lehigh University (USA) and Texas A&M University (USA). He has (co-) authored more than 750 scientific journal publications and has received many scientific awards, including the Royal Dutch Chemical Society Gold Medal, Netherlands Catalysis and Chemistry Award, Paul H. Emmett Award in Fundamental Catalysis, International Catalysis Award, Bourke Award from the Royal Society of Chemistry, Spinoza Award from the Netherlands Organization for Scientific Research, Kozo Tanabe Prize for Acid-Base Catalysis, Chemistry Europe Award, Karl Wamsler Innovation Award as well as the Michel Boudart Award for the Advancement of Catalysis. He is a Knight in the Order of the Netherlands Lion, and an elected member of a.o., the Royal Dutch Academy of Sciences (KNAW), the Royal Flemish Academy of Belgium for Sciences and Arts (KVAB), and the European Academy of Sciences. His research group aims to build a powerful “camera” to record what actually happens in a working catalytic solid under relevant reaction conditions. The aim of this operando spectroscopy and microscopy work is to bring the necessary science and technology to a level that enables imaging catalytic processes at macro, meso and micro scales, from the chemical reactor down to interactions between single atoms and single molecules within a single catalyst particle. This innovative approach allows to unravel the activation and deactivation mechanisms of various catalytic processes, of relevance to make the fuels and chemicals from renewable resources, including CO2, biomass and plastic waste.
