Abstract

The invention discloses a preparation method of a Cu-Cu3P material with a nano array structure. The method comprises the following steps: 1, mixing water, glucose and polyvinylpyrrolidone to obtain a mixed solution; 2, dropwise adding a copper sulfate solution into the mixed solution, and stirring for reaction; 3, centrifuging, washing and drying to obtain a copper nanosheet; 4, adding water, sodium hydroxide and a hydrogen peroxide solution into the copper nanosheet, and carrying out heat preservation reaction; 5, cooling, centrifuging, washing and drying to obtain Cu-CuO material powder with the nano array structure; and 6, separately putting the Cu-CuO material powder with the nano array structure and sodium hypophosphite into a porcelain boat, and calcining to obtain the Cu-Cu3P material with the nano array structure. According to the preparation method provided by the invention, the characteristic that the copper nanosheet slowly releases copper ions in a liquid phase is utilized, CuO is firstly generated on the surface of the copper nanosheet and then converted into Cu3P, meanwhile, a substrate nano Cu sheet is still preserved, and the prepared Cu-Cu3P material with the nano array structure is applied to the fields of catalysts, electrode materials and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of inorganic composite materials, in particular to a nano-array structure Cu-Cu 3 Preparation method of P material. Background technique [0002] Metal phosphide refers to the general term for binary or multi-component compounds composed of metal and phosphorus. It is a type of interstitial compound formed by filling the metal atomic lattice with phosphorus, a non-metallic element with a large atomic radius. Due to its special structure, it has properties that other compounds (covalent compounds, ionic crystals and transition metals) do not have. Compared with other nitrides, oxides, sulfides, etc., phosphides exhibit higher stability, reactivity, etc. Metal phosphides are widely used in optoelectronics, magnetism, and energy storage. [0003] The storage capacity, application cost and redox performance of copper-based materials have obvious advantages over Co, Fe, Ni, etc., so the study o...
