Abstract

The invention provides a method for preparing an efficient and stable ruthenium dioxide-based acidic oxygen evolution electrocatalyst. In the method, carbon cloth is used as a base, ruthenium trichloride solution is dipped and coated on the carbon cloth, and then heat treatment is performed to oxidize ruthenium trichloride into ruthenium dioxide. The obtained ruthenium dioxide is supported on the carbon cloth in the form of nano-scale particles, has the characteristics of high catalytic activity and stable catalytic effect, and can be used as an anode of an industrial acidic water electrolysis hydrogen production device.

Description

technical field

[0001] The invention belongs to the technical field of electrocatalytic oxygen evolution for hydrogen production by electrolysis of water, in particular to a preparation method of an efficient and stable ruthenium dioxide-based acidic oxygen evolution electrocatalyst. Background technique

[0002] Hydrogen is an energy carrier with practical application prospects. Due to the advantages of high energy density, no carbon emissions, abundant sources, and renewable advantages of hydrogen, hydrogen production technology has been extensively studied in recent decades.

[0003] Hydrogen production by electrolysis of water is a commonly used means of hydrogen production. The electrolytic water reaction is divided into two half-reactions, the cathodic hydrogen evolution reaction and the anode oxygen evolution reaction. The oxygen evolution reaction at the anode involves a four-electron transfer process, so the reaction energy barrier is relatively high, which makes t...
