facile synthesis of g-c3n4/nh2-fe-mils for effective degradation of imidacloprid under visible light irradiation

Abstract: mesoporous g-c3n4/nh2-mil-101(fe) composites were successfully made by the solvothermal method. the g-c3n4/nh2-mil-101(fe) composite indicates higher photocatalytic activities than bare g-c3n4 and nh2-mil-101(fe) for imidacloprid degradation. the optimum heterojunction photocatalyst, g-c3n4/nh2-mil-101(fe) (250 mg of mass ratio gc3n4), reveals the highest photocatalytic efficiency up to 80% within 1 h. the response surface methodology (rsm) was used in the design of imc photodegradation experiments to assess the interaction effects of the independent variables and to specify the optimal conditions. eventually, a possible reaction mechanism had also been investigated in detail.
