Herein, visible light active ZnO/Au/RGO ternary nanocomposites were successfully synthesized by Pulsed Laser Ablation (PLA) technique in liquid medium. The photocatalytic activity of as synthesized ternary nanocomposites was evaluated for the degradation of Methylene Blue and Rhodamine-B under visible light irradiation. The synthesized materials were characterized by UV-visible spectrometry, photoluminescence (PL), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD). The optimal ZnO/Au/RGO showed the higher degradation efficiency than bare ZnO. The density of the Au nanoparticle and RGO nano matrix on ZnO could be altered by changing the concentration of gold and RGO as (5%wt, 10%wt, 15%wt) using laser irradiation and photo-deposition technique. This enhanced photocatalytic activity is attributed to the efficient separation and transfer of photo induced electron-hole pairs in ZnO/Au/RGO ternary nanocomposites. The superior photocatalytic activity revealed that the ZnO/Au/RGO ternary nanocomposites could be a promising material for waste water treatment and other environmental remediation applications.
