摘要
研究了CIO纳米粉体的制备。以4N的In、HCl、CuCl2.2H2O、Li2CO3、CuCl等试剂为原料,采用固相法、阳离子交互反应法、化学共沉淀法制备CIO纳米粉体。通过TG-DTA、XRD、SEM、TEM、BET等现代分析测试手段对制备的粉体进行表征。结果表明,固相法制备的粉体晶粒粒径为1μm,比表面积为3.53m2/g;阳离子交互反应法制备的粉体晶粒粒径为30.032nm,比表面积为27.4m2/g;化学共沉淀法制备的粉体团聚少、分散性好,晶粒粒径为27.815nm、比表面积为42.06m2/g,较前2种方法具有优势。
In this paper, the method for fabricating copper indium oxide （CIO） nanometer powders is studied by chemistry coprecipitation method mainly, and by solid state reaction method and cation exchange reaction method. This reagents used are as follows： high purities indium （4N）, CuCl2·2H2O, Li2CO3, CuCl, HCl, In and so on. Measurements such as DTA-TG, XRD, SEM, TEM, BET are used to characterize the superfine particles. Experimental results show that the mean grain size is about 1μm and specific surface area is 3. 53m^2/g by solid state reaction method, and the mean grain size is about 30. 032nm and specific surface area is 27.4m^2/g by cation exchange reaction method, and the mean grain size is about 27. 815nm and good dispersionby and specific surface area is 42. 06m^2/g by chemistry coprecipitation method which is the best way.
