The construction of S-scheme heterojunctions has drawn widespread attention within the photocatalysis field due to their capacity for efficient separation photogenerated carriers, leading excellent photo-oxidation-reduction performance. Herein, a novel loofah biochar/MoS2/g-C3N4 (LB/MS/CN) heterojunction was successfully constructed by ultrasonication in 50% ethyl alcohol and heat treatment N2 atmosphere. Degradation experiments showed that 5% LB/MS/CN ternary photocatalyst had optimal photocatalytic efficiency (96.4%) degradation rhodamine B (RhB), reaction rate (k) this (0.05420 min-1) 5.4 times unmodified CN (0.01001 min-1). Ultraviolet-visible diffuse reflectance spectra, Mott-Schottky, free radical trapping suggested carriers were transferred through structure. Consequently, co-catalytic action LB synergistic impact structure between MS led reduced carrier recombination rate. Furthermore, outstanding stability maintain RhB performance under various environmental conditions (H2PO4-, NO3-, SO42-, HCO3-, NaCl, HA, real water), showing good promise practical applications. Thus, work provides possible strategy purifying wastewater visible light.

With unique photochemical properties, graphitic carbon nitride (g-C3N4) has gained significant attention for application in photocatalytic degradation of a wide range organic pollutants. However, its performance is limited by the rapid electron–hole recombination and relatively weak redox capability. Substantial progress been made preparation g-C3N4-based photocatalysts with enhanced activity. This review summarizes recent advances strategies to improve activity their Morphology control, doping, functionalization, metal deposition, dye sensitization, defect engineering, construction heterojunctions can be used g-C3N4 through promoting charge carrier separation, reducing bandgap, suppressing recombination. Furthermore, oxidants, such as hydrogen peroxide persulfate, coupled enhance generation reactive oxygen species boost Precise control over structure during synthesis process remains challenge, further improvements are required photocatalyst stability mineralization rates More research development effort needed address existing challenges, refine design activity, promote practical pollutant degradation.
