Graphitic carbon nitride (g-C3N4) has emerged as the most favored photocatalyst owing to its intriguingelectronic band structure, stability, cost effectiveness, unique layered structure and facile synthesisprocedure. But, the pristine g-C3N4 suffers from a limited photocatalytic activity because of its low chargecarrier separation efficiency. Construction of a Z scheme photocatalyst could enhance the charge carriersuppression efficiency and increases the photocatalytic performance significantly. In this review, thedesign aspects of g-C3N4 based Z scheme photocatalysts and the considerations in the selection ofsynthesis procedures of g-C3N4 based Z scheme photocatalysts have been analyzed critically. Thecharacterization methods of Z scheme photocatalysts have also been discussed. Further, the recentenvironmental applications of g-C3N4 based Z scheme photocatalysts have been explored. The reviewfinishes with the concluding remarks and a brief discussion on future challenges and prospects of g-C3N4based Z scheme photocatalysts.
