Abstract

The invention discloses a preparation method of a NiV2S4 nanoparticle electrocatalyst and an application of the NiV2S4 nanoparticle electrocatalyst as electrocatalytic cracking hydrogen aquatic production catalysts, and belongs to the field of catalyst synthesis technology and application. Sulfur-rich organic matter is used as a sulfur source; metal vanadium salt is used as a vanadium source; metal nickel salt is used as a nickel source; and the hydrogen production eletrocatalyst with NiV2S4 nanoparticles, uniform chemical composition and electrocatalytic activity in the whole PH electrolyte is obtained through one-step calcination after the constituents are uniformly mixed through a mechanical method. The preparation method has the advantages that the synthetic raw material is cheap, thesynthesis method is simple, the production cost is low, and the controllability is high. NiV2S4 is a novel aquatic cracking hydrogen production electrocatalyst that exhibits hydrogen production catalytic activity to a certain extent within the full pH range (0-14).

Description

technical field

[0001] The invention belongs to the technical field of hydrolysis electrocatalysts, in particular to a NiV 2 S 4 Electrocatalyst and method for its preparation. Background technique

[0002] Due to the shortage of energy and severe environmental pollution in today's society, hydrogen, as a storable, pollution-free and renewable high-quality energy carrier, has been extensively researched and developed. Hydrogen production by electrolysis of water is a large-scale hydrogen production method with simple operation and mature technology; however, the biggest problem at present is the high power consumption and the price of the most effective catalysts such as Pt, Pd and their alloys required for hydrogen production However, some non-noble metal catalysts including nickel or nickel-based materials, metal sulfides, selenides, carbides, nitrides, phosphides, etc. have been developed. Therefore, the development of inexpensive, abundant, and highly active catalysts...
