On the other hand, the heterogeneous photocatalytic oxidation of toluene, in aqueous suspensions of TiO, has been studied with some details, by Fujihira et al. (refs.4-5). These authors have reported that, in aqueous media, up to 2 h of UV-irradiation, benzaldehyde was one of the main products benzyl alcohol was de tected as traces and benzoic acid was not detected (refs.4-5). However, in our experimental conditions using neat-liquid toluene, not only benzaldehyde but both benzyl alcohol and benzoic acid were detected as main products.

A mechanism has been proposed to explain the heterogeneous photocatalytic oxidation of hydrocarbons in oxygen-containing solutions at platinized Ti02. This is based on the photogeneration of hydroxyl radicals at the Ti02 surface [equations (2)—(4), where h" = hole]. However, another paper suggests that the... 

This paper is concerned with an attractive possibility involving both zeolite and semiconductor in photocatalytic oxidation. We study here the heterogeneous photocatalytic oxidation of various alkylbenzenes and unsaturated model compounds using Ti02 and zeolite-added Ti02 as catalyst. The influence of reaction parameters and the effect of zeolite addition are analysed. 

The heterogeneous photocatalytic oxidation of cyclohexane, methylcyclohexane and n-heptane by molecular oxyoen (760 torr), at room temperature, has been carried out on TiO and TiO derivatizM with iron porphyrins.
