Abstract CuS/Au/ZnO core-sell nanorods (NRs) have been synthesized by a novel and facile chemical method in an aqueous medium. The CuS/Au/ZnO NRs showed higher catalytic activity as compared to the ZnO NRs, Au/ZnO NRs, and CuS/ZnO NRs. The wavelength-dependent photocatalytic activity of the CuS/Au/ZnO NRs confirmed that the Au NPs act as the surface plasmon generated photocatalytic activity boosters and that CuS performs as a co-catalyst. The photocurrent generation and photo-electrochemical study further exhibited higher photocurrent generation and reduction of charge transfer resistance due to the synergistic impact of the Au NPs and CuS coating on the ZnO NRs.

表面等离子体热电子与CuS/Au/ZnO核壳纳米棒的CuS纳米层协同作用降解有毒污染物

摘要 CuS/Au/ZnO 核-销售纳米棒 (NRs) 已通过一种新颖且简便的化学方法在水性介质中合成。与 ZnO NRs、Au/ZnO NRs 和 CuS/ZnO NRs 相比，CuS/Au/ZnO NRs 表现出更高的催化活性。CuS/Au/ZnO NRs 的波长依赖性光催化活性证实，Au NPs 作为表面等离子体产生的光催化活性助推器，CuS 作为助催化剂发挥作用。由于 Au NPs 和 CuS 涂层对 ZnO NRs 的协同影响，光电流产生和光电化学研究进一步表现出更高的光电流产生和电荷转移电阻的降低。
