Abstract

The invention provides a novel Co3Mo3C electro-catalyst and an application of the novel Co3Mo3C electro-catalyst in hydrogen production through sea water electrolyzing. Particularly, the prepared Co3Mo3C electro-catalyst is loaded on a nickel foam substrate to form a catalytic hydrogen evolution electrode. The hydrogen production efficiency is improved and the cost is reduced by fully utilizing the high specific area of the foam nickel and the low cost, good electric conductivity and stability and excellent electro-catalytic performance of carbide. In addition, rich sea water resources are fully utilized, hydrogen is produced in the nearly neutral environment, and the service life of the electrode is prolonged. The stability of the catalytic hydrogen evolution electrode with the Co3Mo3C loaded on the substrate is high, the electric conductivity is good, the electro-catalytic activity is superior, the preparation method is easy and convenient to implement, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production by electrolysis, in particular to a novel Co 3 Mo 3 C Electrocatalyst and its application in hydrogen production by electrolysis of seawater. Background technique [0002] At present, although traditional energy sources such as coal, oil, and natural gas still occupy an important position in economic development, due to their limited reserves, finding one or several alternative new energy sources has become an important problem that mankind needs to solve urgently. Among many new energy sources, hydrogen is an abundant, renewable and clean fuel, and electrolysis of water is the simplest method for large-scale hydrogen production, but high-efficiency hydrogen evolution electrocatalysts are needed. At present, Pt is the best hydrogen evolution catalyst, but it is too expensive to be used on a large scale. Both alkaline water electrolysis and acidic water electrolysis based on proton e...
