Photocatalytic Degradation of Organic Pollutants in Water by Polyoxometalates Zhu Xiuhua, Zhu Min, Wang Wei (Department of Environmental Science and Engineering, Dalian Railway Institute, Dalian 116028) Abstract The basic characters of polyacid and research progress on photocatalytic degradation of organic pollutants in water with polyoxometalates were reviewed. Particularly, the photocatalytic degradation mechanism of aqueous chlorinated organic compounds, pesticides and dyes with polyoxometalates and supported polyoxometalates were introduced. The photocatalytic performance and photocatalytic mechanism of polyoxometalates were compared with those by TiO2 and H2O2.
