Synthesis and Photocatalytic Performance of Pd/FeVO₄ Composite Photocatalysts

Abstract:

Pd/FeVO₄ composite photocatalysts were synthesized by the impregnation method.The as-prepared samples were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM).And the obtained samples were characterized by XRD, SEM and BET. The effect of Pd-loaded contents on their photocatalytic activity was studied by photocatalytic oxidation of methyl orange under 20 W UV light irradiation. The mechanism was also analysised. The results show that PdO can remarkably affect the photocatalytic activity.The photocatalyty activity of Pd-loaded FeVO₄ was significantly enhanced and the decolorization rate of MO can be increased 27% more than that of pure FeVO₄ sample when loading content is 3.5wt %.
