- 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.
