Abstract

The invention discloses a method for preparing a porous indium phosphate photocatalytic material. The method specifically comprises the following steps: adding indium chloride into diethyl ether, dissolving with ultrasonic waves, adding polyacrylamide and stirring to obtain a uniform spinning liquid, and electrospinning to obtain indium chloride-containing polyacrylamide nanofibers; placing the obtained indium chloride-containing polyacrylamide nanofibers in a tube furnace, heating in an air atmosphere at a speed of 10 DEG C per min to a temperature of 450 to 500 DEG C, keeping the temperaturefor 3 to 5 h, and then stopping heating, naturally cooling to room temperature to obtain porous indium chloride; placing the resulting porous indium chloride in 50 to 100 mL of a phosphoric acid solution with a concentration of 2 to 20 mg / L, impregnating for 10 to 25 h and then removing the phosphoric acid solution, cleaning with pure water for 2 to 3 times, and drying at a temperature of 60 to 80 DEG C to obtain a porous indium phosphate photocatalytic material. The method provided by the invention has the advantages that 1) the porous indium chloride reacts with phosphoric acid to obtain porous indium phosphate; 2) the porous indium phosphate has high adsorption, a condensation effect on pollutants and high degradation speed.
