Construction of g-C3N4 nanotube/Ag3PO4 S-scheme heterojunction for enhanced photocatalytic oxygen generation

Heterojunction engineering is considered as a hopeful approach to ameliorate the separation of photogenerated carriers of photocatalysts, realizing efficient water-splitting performance. In this study, an organic-inorganic S-scheme of a one-dimensional g-C3N4 nanotube (TCN)/Ag3PO4 photocatalytic system with high photocatalytic water oxidation activity was designed by coupling g-C3N4 nanotubes over Ag3PO4 particles through a chemical...
