Title: CO2 Sequestration and Recycle by Photosynthesis

Abstract

Hydrocarbon oxygenate synthesis from photocatalytic reactions of CO{sub 2} and H{sub 2}O over various catalysts is a very attractive process. However, the formation rate of the hydrocarbons and oxygenates is significantly lower than conventional catalysis. One possible reason for the low rate of product formation is the presence of oxidation sites which reoxidize the products back to CO{sub 2} and H{sub 2}O. For further improvement of catalytic activity for the reduction process, it is essential to understand the oxidation reaction process. We have studied photocatalytic oxidation of methylene blue and found the oxidation rate is significantly higher than the reduction rate.
