摘　　要：本文采用化学沉积法制备了纳米-p-CuO/n-T-ZnOw复合催化剂,讨论了合成体系中聚乙二醇-600(PEG-600)浓度对样品的物相、微观形貌以及光催化活性等的影响。研究结果表明:在合成体系中PEG-600对CuO纳米颗粒沉积在T-ZnOw表面起着重要的作用,随着PEG-600浓度的增加,T-ZnOw表面沉积的CuO纳米颗粒越密集;在紫外光照条件下,合成的样品对亚甲基蓝(MB)和甲基橙(MO)的光催化降解率均明显高于单一T-ZnOw,p型CuO纳米颗粒沉积在n型T-ZnOw表面可以促使光生电子-空穴对发生分离,有效提高T-ZnOw的光催化活性;其中合成体系中PEG-600浓度为0.6 mol/L时制得的样品光催化活性最高。该研究可为简便低成本制备高性能纳米-p-CuO/n-T-ZnOw复合半导体催化剂提供参考。In this paper,the nano-p-CuO/n-T-ZnOw composite catalysts were prepared by chemical deposition method,and the effects of polyethylene glycol-600(PEG-600)concentration in the synthesis system on the phase,microstructure and photocatalytic activity of samples were discussed.The results show that PEG-600 plays an important role in the deposition of CuO nanoparticles on the surface of T-ZnOw in the synthesis system,with the increase of PEG-600 concentration,the denser p-CuO nanoparticles deposited on the surface of n-T-ZnOw.All the compounds exhibit excellent photocatalytic activity in decomposing of methylene blue(MB)and methyl orange(MO)under UV light than that of T-ZnOw,the photocatalytic activity of the samples increase with the increasing of PEG-600 concentration up to 0.6 mol/L,while it decreases when further increasing the PEG-600 concentration.This study is expected to provide a reference for the facile and low-cost preparation of high-performance of nano-p-CuO/n-T-ZnOw composite catalysts.
