Synthesis and Characterization of Ternary Composite g-C3N4-MoO3/rGO for Photocatalytic Activity

Abstract

<p>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 MoO<sub>3, </sub>g-C<sub>3</sub>N<sub>4</sub>, binary composite g-C<sub>3</sub>N<sub>4</sub>-MoO<sub>3,</sub> and ternary composite g-C<sub>3</sub>N<sub>4</sub>-MoO<sub>3</sub>/rGO have been studied in their photocatalytic performance in the degradation of Rhodamine B (Rh-B) was tested and compared. The ternary composite g-C<sub>3</sub>N<sub>4</sub>-MoO<sub>3</sub>/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. </p>
