Abstract:

Under visible light, the catalytic properties of heteropoly acid supported {(NH4)6 H5[Mo4V9O40]•23H2O/TiO2} by sol-gel method are studied and characterized. By exploring different amount of catalyst and oxidant for degrading dye wastewater analog, photocatalytic decolorization rate of the neutral red solution is investigated, and those main effects on the efficiency of catalytic degradation are discussed. The results show that photo-degradation efficiency relies on the amount of catalysts and oxidants, the catalyst is recoverable and readily to recycle.
