Abstract

The invention discloses a preparation method of a porous indium phosphate loaded copper manganate photocatalytic material. The preparation method comprises the following steps: adding indium chlorideinto diethyl ether, dissolving with ultrasound, then adding polyacrylamide, stirring to obtain a uniform spinning solution, and carrying out electrostatic spinning to obtain polyacrylamide nanofiber containing indium chloride; putting the obtained product into a tubular furnace, and heating to 450 to 500 DEG C to obtain porous indium chloride; putting the obtained product into a phosphoric acid solution to obtain a porous indium phosphate photocatalytic material; weighing copper nitrate and manganese nitrate, stirring until the copper nitrate and manganese nitrate are dissolved, then adding acetic acid, stirring until the acetic acid is completely dissolved, adding the porous indium phosphate photocatalytic material, then putting the solution in a water bath for stirring, adding sodium citrate, continuously stirring and carrying out water bath for 6 to 8 hours, separating obtained precipitate, and carrying out calcinations at the temperature of 450 to 505 DEG C to obtain the porous indium phosphate loaded copper manganate photocatalytic material. After porous indium phosphate is loaded with copper manganate, the adsorbing effect is good, and simultaneously, the indium phosphate isbeneficial for promoting the copper manganate to improve the degrading speed.
