Tungsten Oxide

Tungsten oxide is an ideal photocatalyst in transition metal oxide which has properties of high catalytic property, low cost, nontoxic and stable. It is now used to degrade organic pollutant such as ethanal, chloroform and fuel into inorganic material. The principle is degrade it into CO 2  and H 2 O, it has high photodegradation efficient and wide application prospect. According to thermodynamic argument, the electron hole on the surface of tungsten oxide oxidizes the OH- and hydrone into OH- (free radical). OH- has strong oxidation capability, it can oxidize most of organic and inorganic pollutant and degrade them into innoxious substance like CO 2  and H 2 O. On the other side, active electron on the surface of tungsten oxide has strong reducing capability, it can reduce and remove heave metal ion in the water. Early research is mainly about applying nano powder semiconductor catalyst in eliminating pollutant in water, but the recovery of catalyst is difficult...
