Title:
APPLICATION OF TIN DISULFIDE NANOCATALYST IN PRODUCTION OF HYDROGEN BY PIEZOELECTRIC CATALYTIC DECOMPOSITION OF WATER
Document Type and Number:
WIPO Patent Application WO/2023/272413
Kind Code:
A1
Abstract:
Disclosed is an application of a tin disulfide nanocatalyst in production of hydrogen by piezoelectric catalytic decomposition of water. In the prior art, solar energy is utilized to achieve photocatalytic decomposition of water of a semiconductor to produce hydrogen, but conditions required by photocatalysis are relatively complex and energy consumption is relatively high. The present invention provides an inorganic nanomaterial of a copper ion- or silver ion- doped tin disulfide nanoflower. The purpose of catalytically decomposing water to produce hydrogen is achieved by means of ultrasonic treatment without the need for illumination.
