Chemistry Department Seminar

"The Surface Reactions and Photoreactions of TiO2 Single Crystals and Catalysts: The case of hydrogen production."

Presented by Dr. Hicham Idriss, Dept. of Chemistry, University of Aberdeen, UK SABIC T&I, Riyadh, Saudi Arabia

Thursday, April 21, 2011, 1:30 pm — Room 300 - Chemistry Bldg. 555

TiO2 is one of the most studied and understood metal oxide surfaces. It is also one of the most active photo-catalyst known. Its activity covers many typical chemical reactions including oxidation, dehydration, dehydrogenation and carbon coupling. For these reasons it has become a prototype surface for many relevant studies related to biomaterials, environmental remediation and photo-catalysts. In this talk we will cover the processes of adsorption and reaction of model surfaces of TiO2 and compare them to real catalytic materials for some of the above mentioned reactions with emphasis on photoreaction for H2 production from renewables.
