Summary: This study presents a strategy of in situ [SO4] modification and heterojunction construction to design photoelectrodes with multicharge-transfer channels for enhanced PEC performance. The core-shell heterojunction of sulfate-functionalized CdS decorated on ZnO nanorod arrays and Ag2S nanoparticles provides active sites for accelerated charge transfer and improved PEC reaction kinetics. The addition of AO suppresses the photocorrosion of CdS and facilitates efficient separation and transportation of photogenerated charge carriers. The optimized photoanode exhibits high PEC performance, with a maximum photocurrent density 7.75 times higher than that of pristine ZnO photoanode under simulated AM 1.5 solar light illumination.

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.

Summary: A three-dimensional hierarchical CuS-CdS@TiO2 multi-heterostructure with a CuS semiconductor, CdS branches and TiO2 nanorods was designed as a highly efficient photoanode for PEC water splitting. The enhanced PEC performance was attributed to the wide range of solar spectrum absorption in CdS branches, the efficient electron transfer pathway provided by TiO2 nanorods, and the improved separation of electron-hole on the surface of the photoanode facilitated by the p-n junction formed between CuS and CdS@TiO2 heterostructure.

Summary: This study investigated the effects of geometric features, light absorption spectra, and electrochemical active surface area on photoelectrochemical properties. ZnO nanorods were grown on ITO substrates with controlled morphologies and used as a model. The size of the nanorods was adjusted by varying the concentration of a cation surfactant. The results showed that the geometric characteristics and electrochemically active surface area increased together, while the light scattering effect slightly increased due to the random spatial orientation of the nanorods. The large surface area and void space between nanorods improved the photon-to-current conversion efficiency. A maximum photocurrent density was achieved with smaller diameter and length ZnO nanorods, and the charge separation efficiency was improved with a shorter photogenerated hole diffusion distance.
