Abstract Photocatalysts of one-dimensional (1D) MnxCd1-xS nanorods (NRs) were synthesized by decomposing complex precursors. The photocatalytic experiments confirmed that MnxCd1-xS samples presented an enhanced photocatalytic property due to Mn2+ doping. The optimal Mn2+ concentration of x = 0.02 showed the highest photocatalytic performance. Moreover, the Mn0.02Cd0.98S sample had a universal and stable photocatalytic property in the visible light range. We attributed the enhanced photocatalytic activity to the shallow trapping sites and the narrow energy band gap derived from the appropriate Mn2+ doping, which promote efficient charge separation.

通过分解复杂的前驱体来增强 Mn 掺杂的 CdS 催化剂的光催化性能

摘要 通过分解复杂的前体合成了一维 (1D) MnxCd1-xS 纳米棒 (NRs) 的光催化剂。光催化实验证实，MnxCd1-xS 样品由于 Mn2+ 掺杂而表现出增强的光催化性能。x = 0.02 的最佳 Mn2+ 浓度显示出最高的光催化性能。此外，Mn0.02Cd0.98S样品在可见光范围内具有通用且稳定的光催化性能。我们将增强的光催化活性归因于浅捕获位点和由适当的 Mn2+ 掺杂产生的窄能带隙，这促进了有效的电荷分离。
