Highly mesoporous g-C3N4 with uniform pore size distribution via the template-free method to enhanced solar-driven tetracycline degradation

A highly mesoporous graphitic carbon nitride g-C3N4 (GCN) has been produced by a template-free method and effectively photodegrade tetracycline (TC) antibiotic under solar light irradiation. The mesoporous GCN (GCN-500) greatly improves the photoactivity (0.0247 min(-1)) by 2.13 times, as compared t...
