A high recombination rate and low charge collection are the main limiting factors of copper oxides (cupric and cuprous oxide) for the photocatalytic degradation of organic pollutants. In this paper, a high performance copper oxide photocatalyst was developed by integrating cupric oxide (CuO) and cuprous oxide (CuO) thin films, which showed superior performance for the photocatalytic degradation of methylene blue (MB) compared to the control CuO and CuO photocatalyst. Our results show that a heterojunction photocatalyst of CuO-CuO thin films could significantly increase the charge collection, reduce the recombination rate, and improve the photocatalytic activity.
高复合率和低电荷收集率是氧化铜（氧化亚铜和氧化亚铜）光催化降解有机污染物的主要限制因素。本文通过整合氧化铜（CuO）和氧化亚铜（Cu₂O）薄膜开发了一种高性能的氧化铜光催化剂，与对照CuO和Cu₂O光催化剂相比，其对亚甲基蓝（MB）的光催化降解表现出优异的性能。我们的结果表明，CuO-Cu₂O薄膜异质结光催化剂可以显著提高电荷收集率，降低复合率，并提高光催化活性。
