纳米氧化钌的制备及其碳纳米管复合电极的超电容特性 高琦1,梁吉1,王晓峰1 (1.清华大学,北京,100084) 摘要:利用氯化钌和碳酸氢钠为反应前驱体,采用溶胶凝胶方法制备了粒径小于70 nm的超细氧化钌电极材料.将材料在210℃下加热烧结处理后,材料具有良好的表面特性和最大电化学比容量541 F·g-1.当烧结温度在250℃以上时,氧化钌材料明显晶化,同时材料比容量迅速降低.伏安特性测试表明以碳纳米管作为基体制备复合电极可以显著改善氧化钌的容量特性,其中碳纳米管质量分数为20%的复合电极其比容量可以达到860 F·g-1.恒流充放电测试证明氧化钌/碳纳米管复合电极组成的超电容器具有良......
