Formation of Face-Contact Interaction in 2D/2D/2D Heterostructure Ternary Nanocomposites of G-C3n4/mos2/go for Effective Photocatalytic Activity Against the Organic Pollutants under the Visible Light Irradiation

Face-contact heterojunctions in 2D materials effectively separate the charge carriers and enhance the degradation efficiency of the catalyst. In the present work, graphitic-like carbon nitride/molybdenum disulfide/graphene oxide (g-C3N4/MoS2/GO) ternary nanocomposites were synthesized by sonication-assisted hydrothermal method. The surface morphology of g-C3N4, MoS2, and GO seems to be sheet, flower, and layered structure, respectively. Transmission electron microscopy analysis of g-C3N4/MoS2/GO (AT3G15) ternary nanocomposites shows combination of the sheet (g-C3N4) and flower (MoS2) morphologies which combined with the GO-layered structure. The UV–visible absorption spectra of g-C3N4/MoS2/GO ternary nanocomposite were enhanced when compared with AT3G15. The degradation of AT3G15 ternary nanocomposites has been enhanced due to enhancement in photocurrent (1.1 µA) and effectively separates the charge carriers. Thus, AT3G15 ternary nanocomposites enhance rhodamine B dye and of 4-chlorophenol degradation to ~ 99 and ~ 89%, respectively, for 60 min under the visible light irradiation.
