Our research is driven by developing better chemical process and nano-materials (both chemical and bio materials) for industrial application and human beings. We have made use of chemical principles and techniques to understand and explore catalysts and process. We focus on the catalyst preparation and application in petrochemical chemical process.

A variety of techniques are used in our research, including synthetic chemistry, catalyst test and characterisation,  techniques including X-ray diffraction, solid state NMR, Laser Raman, BET surface area, FTIR and electron-microscope.

We have strong track record in developing industrial-oriented catalysts & process , and helped oil industries in trouble-shooting and solution-providing.

Current Position

Technical Director of KACST-Oxford Clean Energy Research Centre (KOPRC),  a joint Centre of Excellence, focus on more efficient petrochemical process and novel catalyst materials.

Founder of Oxford Catalysts Ltd which was floated in London Stock Market in 2006, and now in the name of Velocys, www.velocys.com  

Senior Research Fellow, Chemistry Department, Oxford University
