Construction of direct FeMoO 4 /g-C 3 N 4 -2D/2D Z-scheme heterojunction with enhanced photocatalytic treatment of textile wastewater to eliminate the toxic effect in marine environment

A novel FeMoO /g-C N -2D/2D Z-scheme heterojunction photocatalyst was prepared via wet chemical method. The observed structural morphology of FeMoO /g-C N reveals the 2D-iron molybdate (FeMoO ) nanoplates compiled with the 2D-graphitic carbon nitride (g-C N ) nanosheets like structure. The photocatalytic activity of the g-C N , FeMoO , and FeMoO /g-C N composites were studied via the degradation of Rhodamine B (RhB) as targeted textile dye under visible light irradiation (VLI). The optimal FeMoO /g-C N (1:3 ratio of g-C N and FeMoO ) composite show an enhanced degradation performance with rate constant value of 0.02226 min and good stability even after three cycles. Thus, the h+ and O are the key radicals in the degradation of RhB under VLI. It is proposed that the FeMoO /g-C N Z-scheme heterojunction effectively enhances the transfer and separation ability of e /h pairs, by the way increasing the photocatalytic efficiency towards the RhB degradation. Thus, the newly constructed Z-scheme FeMoO /g-C N heterojunction photocatalyst is a promising material for the remediation of wastewater relevant to elimination of toxic effect in marine environment.
