Abstract

Cerium based titanium dioxide catalysts are made at varying concentrations and cured at different temperatures to develop a new class of photo catalysts that display catalytic activity for volatile organic compound destruction when irradiated with visible light. These catalysts are characterized using X-ray diffractometry, Raman Spectroscopy, UV Vis Diffuse Reflectance Spectroscopy and BET Surface Area analysis. The potential of these catalysts to destroy indoor air volatile organics is evaluated using a tubular reactor flow channel with visible light irradiated interior surfaces through which air contaminated with toluene or decane is reacted. Different preparations of these cerium based titanium dioxide catalysts are evaluated in this flow channel. The kinetics of toluene and decane destruction for the most promising preparation is evaluated. Results of the evaluation of these catalytic surfaces, and kinetic studies are discussed.
