Photocatalytic degradation of organic contaminants by g-C3N4/EPDM nanocomposite film: Viable, efficient and facile recoverable

The original metal free graphitic carbon nitride/ethylene propylene diene monomer nanocomposite film (g-C3N4/EPDM NCF) was fabricated by facile solution cast method. g-C3N4/EPDM NCF with diameter (50mm) and thickness (4mm) was investigated towards the photocatalytic degradation of methylene blue (MB) and methyl orange (MO) dye solution under visible light irradiation. The as synthesized g-C3N4/EPDM NCF was exhibited high crystalline nature with the crystalline size of 21.53nm, the smooth surface nature and the particle size was observed from the TEM analysis is 20nm. Furthermore, the influence of operational parameters was carried out which demonstrated that 100mg photocatalyst and 25μM of dye concentration were obtained as an optimized condition for the best photocatalytic degradation results. As a result of scavenger experiment, it was concluded that the hydroxyl radical (OH) was actively involved in the photocatalytic degradation. The g-C3N4/EPDM NCF were recoverable from the photocatalytic reaction system and the present find findings may open up a new platform for the simple handpicked photocatalyst. •The 100 % recoverable g-C3N4/EPDM NCF was synthesized solution cast method.•The characterization of the materials were confirmed the formation of g-C3N4/EPDM NCF.•Photocatalytic efficiency of g-C3N4/EPDM NCF was evaluated towards the degradation of MB and MO dye solution.•The optimized conditions were found.
