Eu/BiVO(4) composite photocatalysts have been hydrothermally synthesized and characterized by XRD, XPS, SEM, EDS and DRS techniques. The photocatalytic activities of these catalysts were evaluated by the decolorization of methyl orange in aqueous solution under visible light irradiation (lambda>420 nm). It proved that the enhanced activities of Eu/BiVO(4) composites are mainly ascribed to the dopants for the effective electron-hole separation effect, and the optimum content of the doped metal can be controlled by adjusting the ratio of the rare materials in precursor.
Eu/BiVO(4) 复合光催化剂已通过水热合成法制备，并通过 XRD、XPS、SEM、EDS 和 DRS 技术进行了表征。这些催化剂的光催化活性通过在可见光照射下（lambda>420nm）水中甲基橙的褪色来评估。结果表明，Eu/BiVO(4) 复合材料活性的增强主要归因于掺杂剂对有效电子-空穴分离效果的影响，并且可以通过调节前驱体中稀有材料的比例来控制掺杂金属的最佳含量。
