Abstract

The invention discloses a preparation method and application of a MoS2 load plastic hydrogen evolution catalyst. The preparation method of the MoS2 load plastic hydrogen evolution catalyst comprises the sequential steps that plastic is prepared into a plastic carbon matrix A under protection of inert gas; ammonium molybdate, thiourea and powder of the plastic carbon matrix A are dissolved in waterfor forming a solution, then the solution is transferred to a stainless steel high-pressure kettle with a polytetrafluoroethylene lining, and a solution B is obtained, washed and dried for preparingthe MoS2 load plastic hydrogen evolution catalyst. According to application of the MoS2 load plastic hydrogen evolution catalyst, the MoS2 load plastic hydrogen evolution catalyst is used as a catalyst in an industrial electro-catalysis hydrogen evolution reaction. According to the method, the cost of the electro-catalysis hydrogen evolution reaction can be lowered.

Description

technical field [0001] The invention belongs to the technical field of catalyst preparation, and relates to the preparation of a hydrogen evolution catalyst, specifically a MoS 2 Preparation method and application of supported plastic hydrogen evolution catalyst. Background technique [0002] In response to the global energy and environmental crisis, the development of renewable energy technology has become a trend. Hydrogen (H 2 ), as a renewable and environmentally friendly energy with high combustion calorific value, is widely considered to be an ideal substitute for future fossil energy. The rapid development of hydrogen fuel cells further demonstrates the importance of sustainable hydrogen production. Electrocatalytic hydrogen evolution reaction (HER) is a promising method for hydrogen production, utilizing 2H + +2e - =H 2 , where hydrogen ions combine with electrons under the action of an electrocatalyst to generate H 2 . However, in the current electrocatalyti...
