摘要
以三聚氰胺为原料合成了质子化g-C_3N_4,并将其沉积到改性芳纶纤维上,对复合催化剂进行SEM、XRD、FT-IR等表征,结果表明质子化g-C_3N_4成功负载到改性纤维表面。光催化降解亚甲基蓝实验结果表明,75 min内可以将亚甲基蓝降解完全,具有较好的光催化性能。重复性实验表明g-C_3N_4/芳纶催化剂具有很好的稳定性和循环性。
The protonated g-C3N4 is synthesized from melamine and loaded on the modified aramid fiber,and the results of SEM,XRD,FT-IR shows that the protonated g-C3N4 is grafted on the surface of aramid fiber successfully.The catalyst exhibites great photocatalytic ability for methylene blue,which can be degraded completely in 75 min,and it processes good stability and reusability.
