Synthesis and Characterization of Ternary Composite g-C3N4-MoO3/rGO for Photocatalytic Activity
Abstract
The present research prepared a ternary composite g-C3N4-MoO3/rGO using the ultrasonic-assisted wet impregnation method. The prepared photocatalyst was characterized by using Fourier transform infrared spectroscopy (FT-IR), Powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and EDX(Energy dispersive X-ray) techniques. The structure and morphology of pure MoO3, g-C3N4, binary composite g-C3N4-MoO3, and ternary composite g-C3N4-MoO3/rGO have been studied in their photocatalytic performance in the degradation of Rhodamine B (Rh-B) was tested and compared. The ternary composite g-C3N4-MoO3/rGO exhibited better degradation efficiency of 80% than pure and binary composite. The synergistic effect of the three components resulted in enhanced light-capturing ability, high charge separation, and low recombination rate of electron-hole pair.
