The development of high-performance photocatalysts is crucial for enabling efficient CO2 conversion in photocatalytic systems. Here, we developed a novel heterojunction (N-BON) composed Ni-doped Bi4O5Br2 and NiCo2O4 photoreduction with the help simulated sunlight. optimized 21N-BON composite exhibited highest activity, producing 18.66 μmol·g–1·h–1 CO selectivity 95.7%, which represents remarkable 2.15-fold 4.75-fold increase yield compared to Bi4O5Br2/NiCo2O4 Bi4O5Br2, respectively. Photoelectrochemical testing, photoluminescence analysis, theoretical calculations demonstrated that enhanced performance attributed improved photogenerated carrier separation, driven by synergistic effects Ni-doping-induced spin polarization built-in electric field from construction. Additionally, situ DRIFTS analyses was used clarify reaction mechanisms on photocatalyst surface, showing Ni doping adsorption promoted formation key intermediates. This study offers important guidance developing advanced solar-driven reduction, contributing sustainable energy solutions.

Abstract Plasmonic photochemical N 2 fixation has received widespread attention owing to the attractive plasmonic enhancement effects in improving solar‐to‐NH 3 conversion efficiency. However, weak adsorption affinity metallic photocatalysts and insurmountable interfacial barriers metal–semiconductor lead rapid charge carrier recombination instead of participating ‐to‐NH conversion. Herein, a photothermal catalyst Fe‐dispersed MoO 3− x /MXene with synergistic plasmon resonance hybridization structure is fabricated for fixation. The hybrid derived from MXene induce strong optical response across ultraviolet–visible‐near‐infrared range generation energetic carriers, induced effect further accelerates electron extraction, transport, surface reaction kinetics. Moreover, abundant oxygen vacancies Fe sites can intensify donate electrons into anti‐bonding system stimulative NH coupling process. A high NH formation rate 87.1 μmol g −1 h achieved under solar‐level illumination.
