Title:
METHOD FOR PREPARING ADSORPTIVE PHOTOCATALYST
Document Type and Number:
WIPO Patent Application WO/2023/028763
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for preparing a silicon dioxide-coated metal-metal oxide core-shell structured adsorptive photocatalyst. The method comprises the following steps: (1) preparing a single or composite water-soluble transition metal peroxide (ammonium peroxide) precursor; (2) preparing a water-soluble metal-metal peroxide precursor; (3) solventing-out a metal-transition metal peroxide precursor; (4) coating same with mesoporous silicon dioxide; (5) purifying same; and (6) crystalizing same. Further disclosed is a catalyst prepared by using the method and the use thereof. The method according to the present invention has a simple process, good operability and relatively low cost, is suitable for mass preparation, shows potential for industrial production, and has extensive application prospects.
