Comprehensive review on advanced reusability of g-C3N4 based photocatalysts for the removal of organic pollutants

Graphitic carbon nitride (g-C3N4) has attained significant research attention in energy and environmental remediation due to its excellent electronic structure, greater physical and chemical properties, and abundance. However, graphitic carbon nitride faces severe problems because of its high recombination rate and higher mass loss of the catalyst during recovery operations. This review emphasizes the methods to overcome the difficulties associated with recovery and reusability of the g-C3N4 based photocatalyst towards the redemption of pollutants present in wastewater. Different strategies like magnetic g-C3N4 based photocatalysts, immobilized photo catalytic systems, and photocatalytic membranes and their usage in photocatalytic applications are well described. Different preparation strategies of the graphic carbon nitride-based composites are elucidated. The key challenges and future perspectives of adopting these methods for photocatalytic applications are also mentioned.
