Graphitic carbon nitride (g-C3N4) is a remarkable semiconductor catalyst that has attracted widespread attention as visible light photo-responsive, metal-free, low-cost photocatalytic material. Pristine g-C3N4 suffers fast recombination of photogenerated electron-hole pairs, low surface area, and insufficient absorption, resulting in efficiency. This review presents the recent progress, perspectives, persistent challenges development g-C3N4-based materials. Several approaches employed to improve absorption materials including metal non-metal doping, co-doping, heterojunction engineering have been extensively discussed. These approaches, general, were found decrease material's bandgap, increase reduce charge carrier recombination, promote thereby enhancing overall performance. The material widely used for different applications such hydrogen production, water splitting, CO2 conversion, purification. work also identified various limitations weaknesses associated with hinders its maximum utilization under illumination presented state-of-the-art solutions reported recently. summary this would add an invaluable contribution photocatalysis research facilitate efficient light-responsive semiconducting

Multi-drug resistant bacterial infections pose a significant threat to human health. Thus, the development of effective bactericidal strategies is pressing concern. In this study, ternary heterostructure (Zn–CN/P-GO/BiS) comprised Zn-doped graphite phase carbon nitride (g-C3N4), phosphorous-doped graphene oxide (GO) and bismuth sulphide (Bi2S3) constructed for efficiently treating methicillin-resistant Staphylococcus aureus (MRSA)-infected wound. Zn doping-induced defect sites in g-C3N4 results reduced band gap (ΔE) smaller energy (ΔEST) between singlet state S1 triplet T1, which favours two-photon excitation accelerates electron transfer. Furthermore, formation an internal electric field at heterogeneous interface optimizes charge transfer pathway, inhibits recombination electron-hole pairs, improves photodynamic effect g-C3N4, enhances its catalytic performance. Therefore, Zn–CN/P-GO/BiS significantly augments production reactive oxygen species heat under 808 nm NIR (0.67 W cm−2) irradiation, leading elimination 99.60% ± 0.07% MRSA within 20 min. Additionally, release essential trace elements (Zn P) promotes wound healing by activating hypoxia-inducible factor-1 (HIF-1) peroxisome proliferator-activated receptors (PPAR) signaling pathways. This work provides unique insight into rapid antibacterial applications element doping excitation.
