纳米二氧化锰对刚果红的降解性能研究

摘要

采用水热法制备不同形貌的纳米二氧化锰,并用扫描电子显微镜(SEM)对其进行表征.通过对刚果红(CR)的催化降解,考察了其形貌对催化性能的影响.结果表明,不同形貌的二氧化锰对刚果红的催化降解率均可达到50％以上,二氧化锰纳米棒簇甚至可以达到95％以上.%The nano-manganese dioxide with different morphology was prepared by hydrothermal method, and was characterized by scanning electron microscopy (SEM). The catalytic degradation property of the samples to the cogon red (CR) was investigated. The result shows that the degradation rate of different morphology of manganese dioxide can reach 50% , even over 95% of the urchinlike manganese dioxide.
