Solar-assisted photocatalytic degradation of benzoic acid using titanium dioxide as a photocatalyst
The photocatalytic degradation of benzoic acid using titanium dioxide (Degussa P-25) as a photocatalyst has been studied. The effects of various anions, which are common in industrial wastewater, and of the initial pH were also studied. The effect of the presence of low concentration of cations was also studied. From the intermediates detected a photocatalytic degradation pathway for benzoic acid has been proposed.
