The presence of an increasing number organic pollutants in water now poses serious risks to both human health and ecological systems. Many these are persistent non-biodegradable. contamination fresh by harmful substances has compelled researchers develop innovative, efficient, cost-effective remediation techniques materials. Thus, photocatalysis long been recognized as a promising approach tackle environmental the energy crisis. However, semiconductor photocatalysts frequently suffer from defects such photo-generated charge carrier recombination, poor visible light response, slow surface reaction kinetics, which can be remedied modifications with appropriate co-catalysts. Therefore, graphene its derivatives have widely used supports for semiconductors due their distinctive optical, physicochemical, electrical features. This critical review addresses current progress design synthesis graphene/semiconductor photocatalysts, well use photocatalytic degradation hydrogen production. Several influencing parameters addressed, including pH, photocatalyst loading, initial pollutant concentration, wavelength, oxidizing species, all could significant impact on rate pollutant's degradation. Furthermore, recyclability catalyst activity mechanisms thoroughly discussed. Numerous case studies systematically presented. Moreover, future prospects major challenges highlighted.

Graphitic carbon nitride (g-C3N4), with facile synthesis, unique structure, high stability, and low cost, has been the hotspot in field of photocatalysis. However, photocatalytic performance g-C3N4 is still unsatisfactory due to insufficient capture visible light, surface area, poor electronic conductivity, fast recombination photogenerated electron-hole pairs. Thus, different modification strategies have developed improve its performance. In this review, properties preparation methods are systematically introduced, various approaches, including morphology control, elemental doping, heterojunction construction, nanomaterials, discussed. Moreover, applications energy environmental sustainability summarized, such as hydrogen generation, CO2 reduction, degradation contaminants recent years. Finally, concluding remarks perspectives on challenges, suggestions for exploiting g-C3N4-based photocatalysts presented. This review will deepen understanding state art g-C3N4, fabrication, modification, application sustainability.
