Title:
PREPARATION METHOD FOR WATER-CHESTNUT-SHAPED ANTIMONY TUNGSTATE COMPOSITE MATERIAL, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/088050
Kind Code:
A1
Abstract:
A preparation method for a water-chestnut-shaped antimony tungstate composite material, and the use thereof. Water-chestnut-shaped antimony tungstate is prepared by using a hydrothermal method, and is compounded with a monomer photocatalyst by using an electrostatic adsorption method to prepare a water-chestnut-shaped antimony tungstate composite material, and the water-chestnut-shaped antimony tungstate composite material can be applied to the photocatalytic degradation of organic dyes, antibiotics or phenolic pollutants. Water-chestnut-shaped Sb2WO6 with uniform morphology is adjusted and synthesized by using ethylene glycol and water by means of a hydrothermal method, and is organically combined with a monomer photocatalyst with controllable structure morphology and good performance to form a heterojunction structure of Sb2WO6 and the monomer photocatalyst, such that the defects of limited visible-light response and fewer active sites of the monomer photocatalyst are overcome, and the spectral response range of the monomer photocatalyst is improved, thereby achieving efficient visible light catalytic oxidation activity, and improving the photocatalytic degradation performance thereof; and the preparation method has the advantages of a high efficiency, simplicity, economy, etc.
