Title:
PLATINUM/PHOSPHORUS CATALYST, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/118786
Kind Code:
A1
Abstract:
Provided are a platinum/phosphorus catalyst, a preparation method therefor, and an application thereof. The platinum/phosphorus catalyst is prepared by means of the following preparation methods: 1) synthesis of a platinum-carbon catalyst in which a carbon carrier, a surfactant, an alkali, and a solvent are mixed to obtain a base mixture, the base mixture, a reducing agent, and a platinum salt solution are mixed and react, and a solid product obtained thereby is the platinum-carbon catalyst; and 2) phosphating of the platinum-carbon catalyst in which the platinum-carbon catalyst, a phosphate source, and an organic solvent are mixed and react, and a solid product acquired thereby is the platinum/phosphorus catalyst. The platinum/phosphorus catalyst is used as an electrocatalyst in electrochemical hydrogen evolution. Compared with the prior art, the preparation method of the invention controls the surface electronic structure of platinum at a low temperature and low pressure or even at room temperature and normal pressure, thereby acquiring an effective electrocatalytic material easily synthesized by means of a simple process.
