Abstract

The invention discloses a method for preparing photocatalytic materials with silver phosphate loaded on porous indium phosphate. The method particularly includes steps of adding indium chloride into diethyl ether, ultrasonically dissolving the indium chloride and the diethyl ether, then adding polyacrylamide into the indium chloride and the diethyl ether, stirring the polyacrylamide, the indium chloride and the diethyl ether to obtain homogenous spinning solution and carrying out electrostatic spinning to obtain polyacrylamide nano-fibers with the indium chloride; calcining the polyacrylamide nano-fibers with the indium chloride in a tube furnace to obtain porous indium chloride; placing the obtained porous indium chloride in phosphoric acid solution, impregnating the porous indium chloride in the phosphoric acid solution and removing the phosphoric acid solution to obtain photocatalytic materials with the porous indium phosphate; adding the photocatalytic materials with the porous indium phosphate into silver nitrate solution, dropwise adding disodium hydrogen phosphate solution into the silver nitrate solution under continuous stirring conditions, and separating, washing and drying precipitates to obtain the photocatalytic materials with the silver phosphate loaded on the porous indium phosphate. The method has the advantages that mutual promotion effects can be realized by the aid of adsorption characteristics of porous materials and catalytic characteristics of the silver phosphate, and the photocatalytic materials with the silver phosphate loaded on the porous indium phosphate are high in degradation speed.

Description
