Abstract

The invention discloses a cuprous ion cluster compound hydrogen evolution electrode. Raw materials of the electrode comprise a cuprous ion cluster compound, a carbon elementary substance and paraffin. The mass ratio of the cuprous ion cluster compound to the carbon elementary substance is 1:1-5. The ratio of the total mass of the cuprous ion cluster compound and the carbon elementary substance to the mass of the paraffin is 1-5:1. The invention discloses a preparation method of the cuprous ion cluster compound hydrogen evolution electrode. The invention discloses application of the cuprous ion cluster compound hydrogen evolution electrode. Compared with the prior art, the cuprous ion cluster compound is introduced in the paraffin carbon paste carbon, and the electrode has higher hydrogen evolution catalytic activity. The hydrogen evolution electrode is easy to manufacture, good in stability, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of electrocatalysis, in particular to a cuprous ion cluster hydrogen evolution electrode and its preparation method and application. Background technique [0002] With the increasing energy crisis and environmental pollution, the development of various new and renewable energy sources has been highly valued by countries all over the world. regarded as the most ideal energy carrier. However, among numerous hydrogen production technologies, electrocatalytic hydrogen evolution electrodes are widely used in the chlor-alkali industry, electrolytic water industry, and electrochemical hydrogen production. Because the electrode has the disadvantages of poor electrocatalytic hydrogen evolution activity, high hydrogen evolution overpotential, and high energy consumption, it is of great practical significance to research and develop an electrode material with high hydrogen evolution catalytic activity and stability. ...
