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.

This study explores photocatalytic capabilities SnFe2O4/g-C3N4 heterojunction nanocomposite, successfully synthesized from graphitic carbon nitride (g-C3N4) tin ferrate (SnFe2O4) applied to degradation cationic dye brilliant cresyl blue (BCB) an aqueous solution. These two components are particularly attractive due their low cost ease fabrication. Various characterization techniques, including XRD, FTIR, SEM, TEM, were used confirm successful integration SnFe2O4 g-C3N4 phases catalysts. photo-Fenton-like composites was evaluated by under visible LED illumination. Compared pure g-C3N4, nanocomposite demonstrated superior performance. Furthermore, performance is much higher than performances. significant improvement photo-Fenton attributed synergistic effect between as well efficient separation photoexcited electron/hole pairs. recyclability composite toward BCB like also shown. aimed assess modeling optimization removal using nanomaterial. main parameters (photocatalyst dose, initial concentration, H2O2 volume, reaction time) affecting this system modeled approaches: response surface methodology (RSM) based on Box–Behnken design artificial neural network (ANN).

S-scheme heterojunctions have become a hot topic in photocatalysis. Copper (Cu) compounds are versatile family of photocatalytic materials, including oxides (CuO, Cu2O), binary (CuBi2O4, CuFe2O4), sulfides (CuxS, (1 ≤ x 2)), selenides (CuSe), phosphides (Cu3P), metal organic frameworks (MOFs), etc. These materials characterized by narrow bandgaps, large absorption coefficients, and suitable band positions. To further increase the efficiency photoinduced charge separation, Cu-based widely integrated into exploited for hydrogen evolution reaction (HER), CO2 reduction, H2O2 generation, N2 fixation, pollutant degradation. This review comprehensively discusses recent progress heterojunctions, highlights their considerable potential targeted applications sustainable energy conversion, environmental remediation, beyond. The fundamentals transfer, design principles verification tools summarized. Then, describes categorized according to chemical composition, integration applications. In particular, implications transfer mechanism on promoting catalytic activity selected systems analyzed. Finally, current limitations outlooks provided motivate future studies developing novel advanced photocatalysts with high performance studying underlying mechanisms.
