POROUS IRON PHOSPHATE AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2023/221630

A1

A porous iron phosphate and a preparation method therefor. The preparation method comprises the following steps: (1) mixing a ferrophosphorus solution and an aluminum alkali solution for a co-precipitation reaction; (2) subjecting the material obtained in step (1) to solid-liquid separation, so as to obtain a precipitate; (3) reacting the precipitate prepared in step (2) with hydrogen phosphide under heating conditions; (4) after the reaction is finished, cooling the precipitate treated in step (3), and then adding the precipitate to a weak acid solution for soaking; and (5) subjecting the material obtained in step (4) to solid-liquid separation, and then performing aerobic calcination to obtain the product.
