摘要首次利用旋涂法将CuMnO₂纳米晶负载于TiO₂纳米棒阵列薄膜上,制备出光催化性能增强的CuMnO₂/TiO₂复合光催化剂,并考察了样品对亚甲基蓝(MB)的光催化降解性能。研究结果表明,CuMnO₂纳米晶和TiO₂纳米棒之间形成p-n异质结结构,能够有效促进电子和空穴的分离,使得CuMnO₂/TiO₂复合光催化剂具有更高的光催化性能。采用浓度为0.25 g/L的CuMnO₂悬浮液制得的CuMnO₂/TiO₂复合材料的光催化降解效率最高,其光催化效率和表观速率分别为88%和0.298 6 h^-1,较纯TiO₂提高约26%和80%。

Abstract: Aseries of p-type CuMnO₂/n-type TiO₂ heterostructure photocatalysts with enhanced photocatalytic activity were fabricated by spin coating CuMnO₂ nanocrystals on TiO₂ nanorod-array film for the first time. Then, the photocatalytic activity of the obtained CuMnO₂/TiO₂ for degradation of methylene blue (MB) aqueous solution was investigated. It could be found from the results that the prepared CuMnO₂/TiO₂ composite showed superior photocatalytic activity to pure TiO₂. The excellent photocatalytic activity of CuMnO₂/TiO₂ could be ascribed to the formation of p-n heterojunctions between CuMnO₂nanocrystals and TiO₂ nanorods, which ensured the effective separation of photogenerated electrons and holes in CuMnO₂/TiO₂. In particularly, the CuMnO₂/TiO₂ with best degradation performance was prepared from 0.25 g/L CuMnO₂, showing the photocatalytic efficiency and apparent rate of 88% and 0.298 6 h^-1, which were 26% and 80% higher than that of pure TiO₂, respectively.
