Highly efficient pollutant removal of graphitic carbon nitride by the synergistic effect of adsorption and photocatalytic degradation.

Environmental remediation based on semiconducting materials offers a green solution for pollution control in water. Herein, we report a novel graphitic carbon nitride (g-C 3 N 4 ) by one-step polycondensation of urea. The novel g-C 3 N 4 material with a surface area of 114 m 2 g -1 allowed the repetitive adsorption of the rhodamine B (RhB) dye and facilitated its complete photocatalytic degradation upon light irradiation in 20 min. This study provides new insights into the fabrication of g-C 3 N 4 -based materials and facilitates their potential application in the synergistic removal of harmful organic pollutants in the field of water purification.
