Keywords:Semiconductor photocatalyst, Photoelectrochemical Water Splitting
In this study, we used atomic layer deposition (ALD) to grow ZnO and TiO2 seed layer and then used hydrothermal synthesis method to obtain ZnO nanorods (NRs) arrays and anatase-TiO2 branched nanorods (b-NRs) arrays. Finally, a layer of 5 nm-thick Au film was deposited by e-beam evaporator to form agglomerated Au nanoparticles on b-NRs TiO2@ZnO to complete the Au-NPs@b-NRs TiO2@ZnO system. Consequently, Au-NPs@b-NRs TiO2@ZnO system exhibits outstanding photoactivity. This high performance PEC water splitting application is attributed to the synergistic effects of the enhanced visible light absorption, resulting from LSPR of Au-NPs, and the increased separation of photogenerated electron-hole pairs.
