Abstract: Graphitic carbon nitride (g-C3N4) is a group of carbon nitride compounds with a general formula close to C3N4 (though commonly with non-zero quantity of hydrogen) and two important substructures dependent on heptazine and poly (Triazine imide) units which liable upon reaction conditions, display reactivities, properties and degree of condensation. Graphitic carbon nitride has high thermal stability, stable chemical structure, non- dangerous nature and medium band gap, as an interesting unique light dynamic semiconductor photocatalyst. This review exhibits the most recent advancement in formation of graphitic carbon nitride C3N4. Fused nanocomposites were used to investigate the photocatalytic ability for purification of water. The graphitic carbon nitride based nanocomposites were sorted as non-metal doped g-C3N4, noble metals/g-C3N4 heterojunction, transition and post transition metal based g-C3N4 nanocomposite and g-C3N4 without metal nanocomposite. Recently, Graphite carbon nitride (g-C3N4) has gained worldwide attention due to great redox ability, metal free nature, suitable energyd gap and visible response, Graphite carbon nitride (g-C3N4) is more energy efficient than TiO2 and has better photocatalytic ability through solar irradiation because it can absorb visible light directly. Small surface area, insufficient light absorption and fast recombination of hole pairs and photogenerated electron are some drawbacks of pure g-C3N4.
