Ru Ti氧化物是电化学工业中常用的阳极材料之一 ,通常是采用热分解法制备。我们采用溶胶凝胶工艺制备纳米级RuO2 60 % TiO2 4 0 %氧化物材料 ,并对其组织结构特点进行分析。研究表明采用溶胶凝胶工艺获得了金红石型Ru Ti氧化物烧结体 ,未出现金属钌和锐钛矿等副反应产物。所制备的氧化物纳米晶在 4 80℃烧结后 ,其尺寸为 3～ 6nm ;在 60 0℃烧结后 ,尺寸约为 10～2 0nm ;80 0℃烧结后 ,晶粒尺寸约为 30～ 60nm ,大颗粒呈典型的柱状形态
Ru Ti oxide is one of the commonly used anode materials in the electrochemical industry and is usually prepared by thermal decomposition. We use sol-gel process to prepare nano-scale RuO2 60% TiO2 4 0% oxide material, and analyze its structure and structure. The results show that the rutile Ru Ti oxide sintered body is obtained by the sol-gel process, and the side reaction products such as ruthenium and anatase do not appear. The prepared oxide nanocrystals have a size of 3 to 6 nm after sintering at 4 80 ° C, a size of about 10 to 20 nm after sintering at 60 ° C, and a grain size of about 30 to 60 nm after sintering at 80 ° C. , Large particles showed a typical columnar morphology
