Abstract The S‐scheme heterojunction exerts a profoundly positive influence on enhancing carrier separation efficiency and redox capability. However, there are few reports accelerating the reaction rate of photogenerated charge carriers, particularly consumption holes in heterojunction. Herein, an situ construction strategy is employed to construct ultra‐small nonprecious metal NiO (≈2 nm) By incorporating into heterojunctions, photocatalytic hydrogen production performance significantly improved by 380 times, nitrogen fixation enhanced 20 times. Density function theoretical (DFT) calculations, X‐ray photoelectron spectroscopy (in XPS), Diffuse Reflectance Infrared Fourier Transform Spectroscopy DRIFTS) characterization results indicate that incorporation heterojunctions can not only enhance photo‐generated carriers ability but also further promote sacrificial agents, thereby achieving secondary enhancement efficiency. Therefore, (H 2 ) (N markedly improved. successful execution this work provides novel approach material structure design, offering valuable insights for development improvement high‐performance materials.

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.
