Hydroxyl copper chloride material and synthesizing method thereof

Abstract

The invention discloses a hydroxyl copper chloride material and a synthesizing method, and belongs to the field of preparation of IB race hydroxyl chloride materials. The preparation method includes the steps that with copper chloride crystal particles and copper oxide powder being raw materials, firstly, the raw materials are mixed and then ground for two hours; then, at the temperature of 100-180 DEG C, sealed heating is conducted for 12 hours, and after reaction is ended, the raw materials are cooled to have room temperature, and then are ground for 30 minutes-1 hour; the processes of heating, cooling and grinding are repeated 3-4 times, so that hydroxyl copper chloride Cu(OH)Cl powder which is dark green is obtained. The prepared product is the compound Cu(OH)Cl composed of copper, hydroxyl and chlorine which are measured according to the proportion of 1:1:1, and is monoclinic system crystals, wherein the space group is P21 / a; the particle size of the crystals is 0.7-1.5 micrometers. The preparation method has the advantages of being simple and easy to implement and realizing a high crystallinity degree, a high yield of products, small losses, high purity and low costs for reactants.

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...

AI Technical Summary

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
