Decolorization of Methylene Blue by Photocatalyst in the Ag₃PO₄-AgI System

Abstract:

The co-effect of PO₄^3- and I^- on the formation of a heterosturucture photocatalyst in the Ag₃PO₄-AgI system was studied by the co-precipitation method between AgNO₃ and the precipitating agent. The precipitating agent was prepared by varying the mole ratios between Na₂HPO₄ and KI. At 10 mol.% KI, the product showed the mixed phase between Ag₃PO₄ and un-identified phase. For 30 - 90 mol.% KI, the un-identified phase and AgI were detected in the x-ray diffraction patterns. The un-identified phase strongly adsorbed the methylene blue dye. The product prepared from 30 mol.% KI had the highest content of un-identified phase and also showed the highest degree of decolorization in the dark. The photocatalytic properties of products in this system were confirmed by the decolorization of methylene blue under visible illumination.
