| Abstract: In this study, single-crystal ZnIn2S4 nanosheet arrays (NSAs) were synthesized via a facile hydrothermal route for photoelectrochemical (PEC) N2 fixation under a visible light irradiation. The Au nanoparticles (NPs) with average size of 5 nm were deposited onto the edges of ZnIn2S4 nanosheets through a photodeposition method, leading to both the enhancements of visible light harvesting and carrier separation. After optimizing the Au loading amounts, the PEC N2 fixation activity was enhanced significantly from 1.09 to 2.26 μg·cm-2·h-1, which is attributed to the enhancements of visible light absorption and carrier separation. Furthermore, a schematic model was used to clarify the mechanism as had been demonstrated by the photoluminescence (PL) and PEC results, respectively. |
