The chemical composition and structure of the catalyst surface is critical in determining the reactivity and selectivity of a catalyst. The techniques of surface analysis are able to provide the surface information. Electron Spectroscopy for Chemical Analysis (ESCA) and related techniques are the most commonly used methods to characterise the composition of the surface rather than the bulk. As a national facility, HarwellXPS will provide the professional service for catalyst sample tests and data analysis using XPS, UPS, ISS, and Raman etc. A fundamental knowledge and how to use our service will be introduced for those who are interested.
Shaoliang Guan is currently a Research Associate and Co-Investigator at the EPSRC National Facility for Photoelectron Spectroscopy (HarwellXPS), UK. He received his B.S. degree in Applied Chemistry from Beijing University of Chemical Technology (China) and M.Sc. in Chemical Enzymology from Queen’s University Belfast (UK). After that, he received his Ph.D. degree in Electrochemistry from Cardiff University (UK) under the supervision of Prof. Gary Attard in 2015. His research interests include investigating selectively catalytic hydrogenation using electrochemical methods and CO oxy-chlorination reactions with various surface characterization techniques such as X-ray photoelectron spectroscopy and Surface enhanced Raman spectroscopy.
