【摘要】 通过浸渍法合成不同复合量的氧化铜/氧化锌异质结光催化剂，探讨氧化铜复合量对氧化锌结构及光学特性的影响，以罗丹明B(RhB)溶液为模拟污水，考察其光催化性能。结果表明：CuO-ZnO异质结的形成可以促进光生电子与空穴的分离，减小禁带宽度，进而提高光催化剂性能。当CuO质量分数为10%时，光催化性能较佳，在光照60 min后对RhB的降解率达到91%，是纯ZnO的3倍以上。更多还原

【Abstract】 The copper oxide/zinc oxide heterjunction photocatalysts with different CuO contents were synthesized by impregnation method. The effect of CuO content on the structure and optical properties of ZnO were investigated. Rhodamine B(RhB) solution was used as simulated wastewater to evaluate the photocatalytic performance. The results showed that the formation of CuO-ZnO heterojunction could promote the separation of photogenerated electrons and holes, reduce the band gap and improve the performance of ZnO. The 10 CuO-ZnO possessed the best photocatalytic performance,and the degradation rate of RhB reached 91% after 60 min, which was more than 3 times that of pure ZnO.更多还原
