Graphitized carbon nitride (g-C3N4), as a simple and green photocatalytic material, has been widely used in degradation. However, the activity of g-C3N4 was inhibited by poor visible light absorption high photocarrier recombination rate. Metal quantum dots (Qds)/g-C3N4 nanosheets coupled catalysts have attracted more attention Fenton advanced oxidation process due to their charge mobility activ...

Therefore, the development of effective UV–HEV-shielding agents is great importance human health. In this study, semiconducting graphitic carbon nitride (g-C3N4) incorporated into interlayer space mica through intercalation cyanamide subsequent pyrolysis reactions form a se...

Different synthesis temperatures (450–550 °C) were applied to synthesize g-C3N4 with the highest visible-light triggered photocatalytic activity. The best performing photocatalyst was synthesized at 550 °C due created favourable structure that expressed lowest band gap and charge carrier recombination rate. To further improve activity of g-C3N4, different g-C3N4/TiO2 (gCN/TNP) composites varyin...

The origin of the photoactivity in graphitic carbon nitride (g-C3N4) and the strategies for improving its photocatalytic efficiency were systematically investigated using first-principles computations. We found that g-C3N4 composed of tri-s-triazine units (g-CN1) is preferable in photocatalysis, owing to its visible-light absorption and appropriate band edge potentials. Despite the benefit of n...
