摘要/Abstract

摘要：

以CuO纳米片阵列为前体，通过水解-刻蚀法在水热条件下制备出了CuMnO₂纳米片阵列薄膜。由于同时存在具有催化活性的Cu（Ⅰ）和Mn（Ⅲ），CuMnO₂纳米片阵列薄膜对催化H₂O₂氧化降解亚甲基蓝（MB）溶液具有优异的效果。进一步放大实验表明，该CuMnO₂薄膜具有稳定的催化性能。基于基底生长的薄膜催化剂能够解决粉体催化剂容易团聚、分离回收困难和容易造成二次污染等问题，在染料废水处理方面具有很好的工程应用前景。

Abstract:

CuMnO₂ nanoplate arrays on copper foil were successfully synthesized through hydrolysis-etching CuO nanosheet arrays in manganese chloride aqueous solution under hydrothermal conditions. The CuMnO₂ nanoplate array films exhibited excellent catalytic performance for oxidation degradation of methylene blue (MB) dye aqueous solution in the presence of H₂O₂ due to the synergistic effect of catalytic active Cu(Ⅰ) and Mn(Ⅲ). Results of scale-up experiments showed that the CuMnO₂ nanoplate array film catalysts possessed superior stability in catalytic activity. Moreover, the CuMnO₂ nanoplate array catalysts on substrates may avoid problems associated with powder catalysts, such as agglomeration, difficulty in separation and possibly secondary pollution, and thus demonstrate great potential in dye wastewater treatment.

Key words: hydrolysis-etching, synthesis, CuMnO₂, nanostructure, catalysis
