溶剂热法制备不同微米结构的氧化亚铜

Preparation of different micro-structural cuprous oxide by solvothermal method

以乙酸铜为原料,采用溶剂热法合成了球形直径约为2~3μm和八面体粒径大小约为4μm的氧化亚铜颗粒。通过选用不同的还原剂如三乙醇胺和乙二醇,系统研究了不同反应体系中如反应温度、溶剂、原料配比和添加表面活性剂十六烷基三甲基溴化铵（CTAB）对微米结构氧化亚铜晶型与形貌的影响,选出制备氧化亚铜八面体和球形的最佳条件,并初步探讨了氧化亚铜微米颗粒的生长机理。

Cuprous oxide particles with a spherical diameter of about 2 to 3μm and octahedron size of 4μm were synthesized by a solvothermal method using copper acetate as raw materials.The effects of different reaction conditions,including temperatures,solvents,ratios of raw materials,and adding surfactant cetyltrimethylammonium bromide（CTAB）,on crystal structure and morphology of micron cuprous oxide have been systematically investigated by choosing different reductants,and the optimum condition for preparing spherical and octahedral cuprous oxide has been obtained.The growth mechanism of micron cuprous oxide particles is discussed and supposed.
