Synthesis, characterization and evaluation of the photocatalytic performance of Ag-CdMoO4 solar light driven plasmonic photocatalyst |
| 초록 |
Ag-CdMoO4 plasmonic photocatalyst was synthesized in ethanol/water mixture by photo assisted co-precipitation method at room temperature. As synthesized powders were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), UV-Vis Difuse Reflectance Spectroscopy (DRS), X-ray Photoelectron Spectroscopy (XPS) and BET surface area analyzer. Photocatalytic activity was evaluated by performing the degradation experiment over methylene blue (MB) and indigo carmine (IC) as model dyes under simulated solar light irradiation. The results revealed that the Ag-CdMoO4 showed the higher photocatalytic performance as compared to CdMoO4 nanoparticles. Dispersion of Ag nanoparticles over the surface of CdMoO4 nanoparticles causes the surface plasmon resonance (SPR), thereby enhancing the broad absorption in the entire visible region of the solar spectrum. Hence, dispersion of Ag nanoparticles over CdMoO4 nanoparticles could be the better alternative to enhance the absorption of visible light by scheelite crystal family for effective photocatalysis. |
