Abstract

The invention relates to a preparation method and application of nickel sulfide / nickel phosphide formed by epitaxial growth of a one-dimensional nano-wire on a one-dimensional nano-rod. The preparation method comprises the following steps: preparing a nickel sulfide (Ni3S2) nano-rod through a hydrothermal method; then putting the Ni3S2 nano-rod into a tubular furnace and calcining under a PH3 atmosphere; while PH3 gas with strong reducibility is used for displacing S, promoting the epitaxial growth of the nano-wire on the nano-rod; finally, obtaining a one-dimensional / one-dimensional structureassembled Ni3S2-Ni12P5 material. The material plays an important role on electro-catalytic water decomposition anode oxygen evolution reaction. The one-dimensional / one-dimensional nickel sulfide / nickel phosphide material can be used as a working electrode of electro-catalytic oxygen evolution reaction; meanwhile, the one-dimensional / one-dimensional nickel sulfide / nickel phosphide material also can be used for fields including a water electrolysis technology, solar water electrolysis for producing oxygen, carbon dioxide reduction and the like.

Description

technical field [0001] The invention relates to a nickel sulfide / nickel phosphide material assembled with a 1D / 1D nanostructure, which is a multilevel structure in which nanowires are epitaxially grown on nanorods. This product has a very important application in the electrocatalytic water splitting anode oxygen evolution process, and also has potential application value in the fields of environmental protection and clean energy. Background technique [0002] With the gradual shortage of fossil energy and the aggravation of environmental pollution, renewable energy conversion and storage technologies have attracted more researchers' attention. Electrocatalytic water splitting is an important method for producing clean energy. Due to the slow kinetic reaction process, the anodic oxygen evolution reaction (OER) greatly limits the development of this technology. Yttrium oxide (IrO 2 ) and ruthenium oxide (RuO 2 ) As a classic OER material, its high cost and scarcity prevent...
