The original metal free graphitic carbon nitride/ethylene propylene diene monomer nanocomposite film (g-CN/EPDM NCF) was fabricated by facile solution cast method. g-CN/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-CN/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-CN/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.
采用简便的溶液浇铸法制备了原始的无金属石墨相氮化碳/三元乙丙橡胶纳米复合膜（g-CN/EPDM NCF）。以直径（50mm）和厚度（4mm）的 g-CN/EPDM NCF 为研究对象，在可见光照射下，对亚甲基蓝（MB）和甲基橙（MO）染料溶液进行光催化降解。所合成的 g-CN/EPDM NCF 表现出高结晶性，结晶尺寸为 21.53nm，TEM 分析表明表面光滑，颗粒尺寸为 20nm。此外，还进行了操作参数的影响研究，结果表明，在最佳光催化降解效果下，100mg 光催化剂和 25μM 的染料浓度为最佳条件。通过猝灭实验得出结论，羟基自由基（OH）积极参与了光催化降解过程。g-CN/EPDM NCF 可从光催化反应体系中回收，本研究结果可能为简单的手动挑选光催化剂开辟了一个新的平台。
