[0002] Photocatalytic oxidation is a method that combines ultraviolet radiation (UV) and oxidants. It uses ultraviolet light to excite nano-titanium dioxide (TiO2) semiconductor catalysts. The electrons in the valence band of the semiconductor absorb light energy and are excited to the conduction band, resulting in the generation of negatively charged highly active electrons in the conduction band and positively charged holes in the valence band, forming an oxidation-reduction system.
