Onion-like carbon modified porous graphitic carbon nitride with excellent photocatalytic activities under visible light
Source abstract
Abstract
Abstract A series of onion-like carbon modified porous g-C 3 N 4 (OLC/pg-C 3 N 4 ) composites have been fabricated by a simple ultrasonic adsorption approach. The resultant OLC/pg-C 3 N 4 composites exhibit excellent photocatalytic activity and stability towards the degradation of the dyes and phenol in aqueous solution under visible-light irradiation. The composite with 2.0 wt% OLC content shows the optimal photocatalytic activity for degrading rhodamine B (RhB), its rate constant is about three times that of pure pg-C 3 N 4 . The improved photocatalytic activity is mainly attributed to the synergetic effect of pg-C 3 N 4 and OLC, including larger surface area, stronger visible light adsorption and efficient separation of photogenerated electrons and holes. Moreover, a possible mechanism of photocatalytic reaction over OLC/pg-C 3 N 4 composite is proposed.
