Title:
NANOGOLD-LOADED TUNGSTEN OXIDE-SILVER SULFIDE COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/045082
Kind Code:
A1
Abstract:
The present invention relates to a nanogold-loaded tungsten oxide-silver sulfide composite material and a preparation method therefor and an application thereof. The method comprises: hydrothermally growing a WO3 nanometer square sheet on FTO glass by means of a solution method; then growing Ag2S on the surface of the WO3 nanometer square sheet by means of a chemical bath deposition method; and finally, depositing on Ag2S/WO3 by means of a constant potential, and performing constant potential deposition of Au nanoparticles to prepare the nanogold-loaded tungsten oxide-silver sulfide composite material. The composite material also has good absorbance in a visible light region, can avoid inactivation of biomolecules caused by ultraviolet light, and can be applied to photoelectrochemical detection of tumor markers CA15-3.
