Modification of porous g-C3N4 nanosheets for enhanced photocatalytic activity: In-situ synthesis and optimization of NH4Cl quantity

In this study, porous g-C3N4 (pg-CN) nanosheets were prepared by a simple and single-step thermal decomposition technique using NH4Cl. The structural and optical properties of the nanosheets were carefully studied. The investigations revealed that the NH4Cl imparted good exfoliation properties to the pg-CN nanosheets. Visible light harvesting was improved and the bandgap also decreased for the pg-CN nanosheets compared to bulk pg-CN. The pg-CN nanosheets showed better degradation percentage of RhB over bulk pg-CN.
