Title:
PLATINUM SINGLE ATOM/CLUSTER MODIFIED PHOTOSENSITIZING SYSTEM, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/245910
Kind Code:
A1
Abstract:
The present invention relates to a photocatalyst for overall water splitting under near-infrared light, in particular to a platinum single atom/cluster modified photosensitizing system, and a preparation method therefor and the use thereof. The preparation method comprises: first constructing a nickel phytate complex on the surface of carbon nitride by means of in-situ chelation or electrostatic adsorption to obtain a nickel phytate/carbon nitride composite system; and then, under the conditions of near-infrared light, subjecting platinum single atoms/clusters to selective photodeposition on the surface of carbon nitride in the nickel phytate/carbon nitride composite system by means of photosensitization to obtain a photocatalyst, and using same in an overall water splitting reaction under near-infrared light. The present invention has the following advantages: platinum single atoms/clusters can be obtained without additional high temperature, additional electric field and expensive and complex equipment; the obtained catalytic active sites are in one-to-one correspondence to the catalytic reaction process instead of being randomly distributed; and the loading of the platinum single atoms/clusters into a photosensitizing system is achieved by means of low-energy-consumption near-infrared light for the first time.
