Intermediate-hydrothermal strategy of carbon doped g-C3N4 for improved photocatalytic degradation and disinfection capacity

Photocatalysts based on C doped g-C3N4 were fabricated via forming intermediate in hydrothermal followed by further calcination and evaluated their performance of photodegradation activity and antibacterial property under visible light irradiation. Experimental results expose that the C atoms replace the N-(C)(3) coordinated N position forming C-(C)(3) bonds. The C doped g-C3N4 shows excellent photocatalytic activity, deriving from the appearance of intermediate structure, thus endowing g-C3N4 with enhanced adsorption energy, extended pi-conjugated system, and broad visible-light absorption region. The photodegradation results of multiple cycles and different pH conditions make clear the stability of C doped g-C3N4 catalyst, highlighting its practical application. The study provides a reference on designing high-activity catalysts by using hydrothermal reaction as middle transitional process.
