Document Type and Number:
WIPO Patent Application WO/2023/272412
Kind Code:
A1
Abstract:
Disclosed in the present invention are a metal ion-doped tin disulfide nanoflower and an application thereof in piezoelectric catalytic degradation of pollutants. A metal salt is placed in a precursor solution containing a tin source and a sulfur source, centrifugal washing is performed after a solvothermal reaction, and drying is performed to obtain a metal ion-doped tin disulfide nanoflower. In the present invention, a copper ion- or silver ion-doped tin disulfide nanoflower is prepared by means of a simple solvothermal method, and applied to the field of piezoelectric catalysis for the first time; the nanosheet morphology and doping synergistically improve the sensitivity of the material to sense mechanical energy and improve the piezoelectric property, thereby improving the catalytic performance. The purpose of catalytic degradation of phenolic organic pollutants in water is achieved by ultrasonic treatment without light.
