【摘要】 研究了经高温焙烧结合高速球磨处理后的碳纳米管的结构及形貌,测定了其相应的比表面积．对碳纳米管冷压成形制得的电催化电极的表面形貌进行了分析．分别以活性炭、石墨、碳纳米管作为电催化阳极,处理模拟染料废水活性艳红X-3B溶液,实验结果表明：碳纳米管电极电催化稳定性较好,经电催化氧化反应20min后,X-3B染料的降解率达到96．55％,其电催化降解效率明显优于活性炭和石墨电极．更多还原

【Abstract】 The structure and morphology of carbon nanotubes modified by high-temperature calcination and miling with high speed were studied.The surface area of carbon nanotubes was measured.The morphology of the carbon nanotubes electrocatalytic electrodes pressed at normal temperature was observed.Active red X-3B simulated wastewater was disposed by active carbon, graphite and carbon nanotubes electrocatalytic electrodes,respectively.The experimental results show that the stability of carbon nanotubes electrodes is good and the dye degradation of X-3B can reach 96.55%.The efficiency of carbon nanotubes electrodes is obviously better than that of active carbon and graphite electrodes.更多还原
