Abstract：Synchrotron technology is nowadays a powerful tool for catalysis studies. It allows one to study the catalysis phenomena in atomic levels during catalyst activation and reaction processes. This presentation explains two methods: X-ray absorption spectroscopy (XAS) and pair distribution functions (PDF) and their uses in the development of a catalyst for CO₂ reforming of CH₄. We have developed a Ni-Co/MgAlOx catalyst which can effectively suppress or minimize the carbon formation in CO₂ reforming of CH₄ reaction. With the use of synchrotron technology such as X-ray absorption spectroscopy and pair density distribution in catalysis study, this presentation will try to answer the following questions:

1) Is the catalyst preparation method developed the sole one to synthesize the right catalyst material?

2) How to formulate the active metallic nanoparticles in the right size during catalyst reduction?

3) What roles does the second metal Co play during the formation of metallic nanoparticles?

4) Has Ni-Co alloy formed during catalyst reduction?

Curriculum Vitae：

Dr. Hui Wang is an associate professor in the Department of Chemical and Biological Engineering of the University of Saskatchewan. He received his B.Sc. and M.Sc. from Taiyuan University of Technology and Ph.D. from University of Alberta. With experience working in industry, universities in China, Australia and Canada, and a US national laboratory, Dr. Wang’s expertise covers heterogeneous catalysis, separation engineering, chemical reaction engineering, and synchrotron X-ray absorption spectroscopy studies in catalysis. He has been involved in the projects of developing carbonyl sulfide hydrolysis catalyst, H₂S scavenger and sulfur removal technology. The method he and his co-workers developed to make CO₂ reforming of CH₄ catalyst, which allows long-term stable operation by minimizing the carbon formation side reaction, has been awarded a US patent. Dr. Wang and his group are also investigating hydrogen production from splitting H₂S, mercury capture using cheap adsorbents, and catalytic combustion efficiency. Dr. Wang has authored and co-authored over 100 publications including journal papers, book chapters, invited and keynote lectures, conference papers and presentations, and research reports. He recently received the Award of Innovation from the Innovation Place of City Saskatoon and the Industrial Liaison Office of University of Saskatchewan.
