Highly Enhanced Visible-Light-Driven Photoelectrochemical Performance of ZnO-Modified In₂S₃ Nanosheet Arrays by Atomic Layer Deposition.

ABSTRACT: Photoanodes based on In₂S₃/ZnO heterojunction nanosheet arrays (NSAs) have been fabricated by atomic layer deposition of ZnO over In₂S₃ NSAs, which were in situ grown on fluorine-doped tin oxide glasses via a facile solvothermal process. The as-prepared photoanodes show dramatically enhanced performance for photoelectrochemical (PEC) water splitting, compared to single semiconductor counterparts. The optical and PEC properties of In₂S₃/ZnO NSAs have been optimized by modulating the thickness of the ZnO overlayer. After pairing with ZnO, the NSAs exhibit a broadened absorption range and an increased light absorptance over a wide wavelength region of 250-850 nm. The optimized sample of In₂S₃/ZnO-50 NSAs s
