Abstract

The invention belongs to the technical field of electrocatalysis and particularly relates to an iron-doped bimetal phosphide electrocatalyst and a preparation method and application thereof. A hydroxide precursor synthesized by a hydrothermal reaction undergoes a phosphating reaction at a low temperature to produce a Ni1CoxFeyP nanosheet array electrocatalyst. The bimetal phosphide has low chargetransfer resistance and a reaction barrier for a hydrogen evolution reaction and has superior performances in the electrocatalytic hydrogen evolution reaction. The catalyst has a low cost. The preparation method is easy to operate and has simple processes. The electrocatalyst has excellent catalytic performances and provides the basic application research for the material in the field of electrocatalysis.

Description

technical field

[0001] The invention belongs to the technical field of electrocatalysis, and in particular relates to a self-supporting iron-doped bimetallic phosphide electrocatalyst with high-performance electrochemical water splitting and its preparation method and application. technical background

[0002] With the continuous consumption of fossil fuels, in order to meet today's huge energy demand, various new energy output plans have attracted extensive attention. As a clean energy without any pollution, hydrogen energy is expected to become the most effective substitute for fossil fuels. Electrochemical water splitting to produce hydrogen (hydrogen evolution reaction, HER) has great application prospects in the development of chemical energy storage technology due to its high efficiency, environmental friendliness, high gas purity and strong adaptability to energy fluctuations. In order to further reduce the overpotential of water splitting, reduce the energy consumed...
