This paper systematically reviewed graphitic carbon nitride (g-C3N4),a key material in the field of photocatalysis.It introduced the primary methods currently used to synthesize g-C3N4 photocatalysts.Addressing the shortcomings of pure g-C3N4—such as low photogenerated charge carrier separation efficiency and narrow light absorption range—the paper delved into core modification strategies for g-C3N4.These strategies included elemental doping,heterostructure construction,and co-catalyst loading,while reviewing research progress and application outcomes for each modification approach.It further identified existing challenges in practical applications of g-C3N4 materials and outlined future research priorities and directions for g-C3N4.
