摘要：
Photocatalytic oxidation of ethanol on Pt/TiO2 and Nafion coated TiO2 catalysts were studied using in situ infrared IR techniques. Infrared studies show that the reaction produced acetaldehyde, acetic acid, acetate, formic acid, formate, and CO2/H2O. Modification of the TiO2 catalyst by Pt and Nafion slowed down the oxidation reaction through site blocking. Incorporation of Pt was found to favor formation of formate (HCOO-), indicating Pt decreases the rate of oxidation of formate more than that of its formation.
