Phototransformation of Nitrogen Containing Organic Compounds over Irradiated Semiconductor Metal Oxides. Nitrobenzene and Atrazine over TiO2 and ZnO

The photocatalytic behaviour of nitrobenzene and atrazineover titanium dioxide and zinc oxide has been compared. Whereas the final products are the same, the intermediate distribution depends on the semiconductor nature. Both nitrate and ammonium ions are formed; nitrite represents a noticeable product in the early part of nitrobenzene degradation.
