What is Photocatalytic Degradation of Trinitrotoluene: Reductive and Oxidative Pathways about?

The photocatalytic degradation of trinitrotoluene and Ihe nilrated benzencs trinitrobenzene and dinitrobenzene on exposure to U~/light, using titanium dioxide as catalyst, follows reducfiv¢ and oxidative pathways. The attack by reducing species is enhanced ia the presence of alcohols, such as methanol. The oxidative derivatization of ~nitrotoluene in these conditions leads to trinim~oenzene, which is fi,~,~er degraded mainly by ~edaetion to amino-nitro compoun&g. In the absence of titanium dioxide, the direct ~hemical d~on of~e chemicals yields :ira same intennediates, but with much lower reaetio~ ra~es. Photocatalytic treatment appears to be a useful alt~mativ¢ torkt water of nitmatomatic pollution. © [997 Elsevier Science S.A.
