Summary: ZnO nanosheets, 2D/1D ZnO/CdS hybrid, and ternary ZnO/CdS/GO S-scheme heterojunction photocatalyst were fabricated using a low-temperature hydrothermal technique. The addition of CdS and GO significantly improved the photocatalytic activity of ZnO, as demonstrated by the higher dye degradation rate constant and the increased visible light absorption. CdS also regulated the size and distribution of ZnO nanosheets, increasing the specific surface area of the sample. The presence of CdS and GO promoted the rapid separation of photoexcited carriers in ZnO, and GO further enhanced the transmission rate of electrons and the photoelectric stability of the ZnO/CdS heterogeneous photocatalyst.

Summary: 3D-ordered porous CdS/AgI/ZnO nanostructures were designed for high-performance photoelectrodes in PEC water-splitting. They exhibited advantages of large surface area, high absorption in visible-light, fast carrier separation and transportation due to a ladder-like band arrangement. The nanostructures were fabricated using a three-stage experiment involving electrochemical deposition, wet chemical method, and deposition-precipitation. The highest efficiency achieved for the CdS/AgI/ZnO nanostructures was 5.2%, significantly higher than other photoelectrodes tested. The improved performance is attributed to enhanced charge separation and transport caused by the unique band arrangement in the ternary nanostructures.

Summary: A new CdS@ZnO core-shell nanorod array was successfully constructed by atomic layer deposition (ALD) for efficient H2 evolution from photoelectrochemical water splitting. The CdS@ZnO200 obtained after 200 ALD cycles showed a significantly enhanced PEC H2 evolution rate of 21.64 μmol·h-1·cm-2, which was about 9.4 times higher than pristine CdS NRAs. The improved performance could be attributed to the Z-scheme charge transfer mechanism between CdS core and ZnO shell, as well as the reduction of charge carrier transfer resistance due to the close contact between the two semiconductors.
