Abstract
Catalytic activities of graphitic carbon nitride (g-C3N4) are restricted thanks to inadequate visible light absorption and high rate electron–hole recombination. In this work, we synthesized porous g-C3N4using polycondensation process. Structural and physico-chemical characteristics of the prepared g-C3N4materials were studied via XRD, DRS, PL, FTIR, Raman spectroscopy, SEM, BET and CHN elemental analyzer. The prepared samples exhibited surprising catalytic activity for the photo-oxidation of rhodamine-B (RhB) in visible light irradiation. From the fabricated g-C3N4materials, the g-C3N4-550 showed photodegradation efficiency of 100% towards the RhB pollutant in water within 30 min. No appreciable decrease of the photocatalytic efficiency of g-C3N4was observed up to five consecutive cycles, confirming the synthesized g-C3N4was highly stable. Thus, this work gave a simple process for large scale production of highly visible light responsive and stable g-C3N4materials used for environmental remediation.
