Abstract

The invention relates to a method for preparing pompon-like copper oxide. The pompon-like copper oxide with uniform size distribution is obtained by using a hydrothermal method under the condition of different aging time. According to the method, a microwave-heating energy supply mode is adopted in an innovative manner, so that the method has the advantages that the operation is simple, convenient, quick and safe, the cost is low and the repeatability is good. The pompon-like copper oxide prepared by the method has a relatively large specific surface area and can be applied to the catalytic decomposition of ammonium perchlorate and the photocatalytic degradation of organic dyes.

Description

technical field [0001] The invention belongs to the preparation of copper oxide, and relates to a preparation method of pompom-shaped copper oxide. The method utilizes hydrothermal reaction, and on the basis of controlling the concentration of reactants, reaction temperature and reaction time, a fluffy copper oxide with uniform shape and size is obtained. This material is expected to be further used in catalytic reactions and photodegradation of organic dyes. Background technique [0002] It has been confirmed that copper oxide (CuO) is a multifunctional material that can be used in many fields, such as catalysts, gas sensors, lithium-ion batteries, and water treatment (L.P.Xu, S.Sithambaram, Y.S.Zhang, C.H.Chen, L. Jin, R. Joesten, S. L. Suib, Chem. Mater. 21 (2009) 1253). Obviously, the functional performance of nanomaterials has a great relationship with its size and shape. In recent years, a lot of scientific research work has been devoted to the synthesis of copper ox...
