Abstract Hydrogen peroxide (H 2 O ) is one of the 100 most important chemicals in world with high energy density and environmental friendliness. Compared anthraquinone oxidation, direct synthesis H hydrogen oxygen (O ), electrochemical methods, photocatalysis has characteristics low consumption, easy operation less pollution, broad application prospects generation. Various photocatalysts, such as titanium dioxide (TiO graphitic carbon nitride (g‐C 3 N 4 metal‐organic materials, nonmetallic have been studied for production. Among them, g‐C which are simple to synthesize functionalize, attracted wide attention. The electronic band structure shows a bandgap 2.77 eV, valence maximum 1.44 V, conduction minimum −1.33 theoretically meets requirements In comparison semiconductor materials like TiO (3.2 eV), this material smaller bandgap, results more efficient response visible light. However, photocatalytic activity yield were severely inhibited by electron‐hole pair recombination rate, utilization rate light, poor selectivity products. Although previous reviews also presented various strategies improve production, they did not systematically elaborate inherent relationship between control their structure. From point view, article focuses on engineering latest research progress On basis, strategy production proposed through morphology control, crystallinity defect, doping, combined other strategies. Finally, challenges industrialization discussed envisioned.

Abstract In this study, a new type of oxycarbide-based compounds, namely lanthanum titanium oxycarbide and neodymium oxycarbide, were synthesized through solid-state reaction to replace due its rapid charge carrier recombination limited responsiveness visible light in photocatalysis. The structural, morphological, optical absorption vibrational properties the catalysts thoroughly characterized using powder X-ray diffraction, scanning electron microscopy, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy assess their suitability for catalytic applications. Subsequently, photocatalytic behaviour materials was evaluated ability degrade hazardous Congo red dye various types water, including deionized domestic utility water used household purposes, seawater, under illumination. Notably, exhibited superior degradation efficiencies dye, achieving maximum rates 87% 89%, respectively, routine purposes within duration 90 minutes, when compared TiOC. However, efficiency slightly lower seawater. Additionally, demonstrated promising hydrogen evolution activity, generating 19.7 21.1 µmol/g, 180 minutes. enhanced removal generation activity has been attributed synergistic effects improved absorption, higher exciton separation supportive pH environment presence lanthanum, carbon ions combined entity.
