Abstract
Photooxidation of Salicylic Acid with bare TiO₂ and metal-modified TiO₂ has been studied in a stirred photochemical reactor that was cooled by a water system by irradiation with a 400 W high-pressure mercury lamp. The effects of the amount of copper and silver coated on TiO₂ and of the temperature on the rate of oxidation have been investigated. An optimum loading of 5% Ag or 5% Cu was observed for photooxidation of salicylic acid.
