Problems solved by technology

Most hydroxy halides are synthesized by hydrothermal method. Although this method is simple and feasible, there are still many disadvantages, such as: the pH value needs to be adjusted during the synthesis process, other by-products are easily generated, the yield of the product is low, and the crystallinity is not high. , Unstable chemical properties, excessive reactants and some reactions also have specific requirements on temperature, which requires hydrothermal synthesis at high temperature to reduce the service life of the reactor

Abstract

A copper hydroxychloride material and a synthesis method thereof of the invention belong to the field of preparation of IB group hydroxychloride materials. The preparation method uses copper chloride crystal particles and copper oxide powder as raw materials. Firstly, the raw materials are mixed and ground for 2 hours; then sealed and heated at 100-180°C for 12 hours. Grinding for 1 hour; repeating the above-mentioned heating, cooling and grinding process for 3 to 4 times to obtain dark green copper hydroxychloride Cu(OH)Cl powder. The prepared product is a compound Cu(OH)Cl composed of copper, hydroxyl and chlorine in a ratio of 1:1:1. It is a monoclinic crystal with a space group of P2 1 / a; the particle size of the crystal is 0.7-1.5 μm. The invention has the advantages of simple operation, good crystallinity, large output of products, less loss, high purity, low cost of reactants and the like.

Description

technical field [0001] The invention belongs to the field of preparation of IB group hydroxychloride materials, in particular to a simple, novel and efficient method for preparing copper hydroxychloride (Cu(OH)Cl) powder. Background technique [0002] In recent years, hydroxy halides have become potential new functional materials due to their simple and diverse preparation methods, easy control of morphology, strong oxidation resistance, stable existence in air, and unique electronic energy band structure. Most of the metal hydroxy halides are M(OH)X and M 2 (OH) 3 The form of X exists. The commonly defined M(OH)X (where M==Mg, Co, Ni, Cu, Zn, Cd, and Hg and X=Cl, Br, or I) can be regarded as one of the metal ion hydroxides The hydroxide ion is replaced by a halide ion, or a halide ion in a metal ion halide is replaced by a hydroxide. m 2 (OH) 3 X (wherein M=Cu, Co, Ni, Fe, Mn and X=Cl, Br, or I). At the same time, M 2 (OH) 3 X This type of compound has attracted mu...
