Photoelectrochemical nitrate reduction has been a promising method for ammonia (NH3) production under normal temperatures and neutral conditions. However, hydrogenation is key process in the selective of NH3 during reduction; therefore, inducing active hydrogen inhibiting are noteworthy problem. In this study, BiVO4/CuS (BVO/CS) heterostructure constructed photoelectrochemical reaction (PEC NIRR). The introduction CuS optimizes electron-transfer ability enhances surface catalytic kinetics BVO/CS. At same time, presence sulfur vacancies on promotes adsorption activation nitrate, realizes splitting H2O, successfully generates abundant radicals (H*). generated H* effectively utilized NIRR. yield selectivity optimal BVO/CS reach 30.55 μg h-1 cm-2 43.8%, respectively, which 2.65 2.39 times that bare BVO. Therefore, work determines role hydrogenation, providing novel strategy boosting PEC CuS/BiVO4 was fabricated reduction. Sulfur defects enabled generation radicals, promoted production.

Abstract Regulating competitive reaction pathways to direct the selectivity of electrochemical CO 2 reduction toward a desired product is crucial but remains challenging. Herein, switching from HCOOH achieved by incorporating Sb element into CuS, in which Cu−S ionic bond coupled with S−Sb covalent through bridging S atoms that elongates 2.24 Å 2.30 Å. Consequently, CuS shorter exhibited high for producing HCOOH, maximum Faradaic efficiency (FE) 72 %. Conversely, Cu 3 SbS 4 characterized an elongated most pronounced production FE 60 In situ spectroscopy combined density functional theory calculations revealed altered length and local coordination environment make *HCOO binding energy weaker on compared CuS. Notably, volcano‐shaped correlation between adsorption strength *COOH indicates as double‐active sites facilitates *COOH, thus results CO.
