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.
