文摘
- •
g-C3N4-N-TiO2 heterojunction was in situ synthesized by a simple heating process.
- •
g-C3N4-N-TiO2 heterojunction exhibits significantly enhanced CO evolution activity and selectivity in CO2 photoreduction process.
- •
CT-70 composite exhibits 4.2 times higher CO yield than P25, and 3.2 times higher CO yield than pure porous g-C3N4.
- •
The doped nitrogen species, porous structure and composite structure greatly promote charge separation.
