Ag3PO4/Bi2WO6复合材料的制备及可见光降解罗丹明B

Fabrication of the Ag_3PO_4/Bi_2WO_6 Composite for the Visible Light Photocatalytic Degradation Rhodamine B

以Bi_2WO_6为载体,通过沉淀法成功制备了Ag_3PO_4/Bi_2WO_6复合材料。同时,通过X-射线粉末衍射和紫外-可见漫反射光谱等检测技术对复合材料的组成结构和光吸收性质进行了全面表征。随后通过可见光降解染料罗丹明B来评价复合材料Ag_3PO_4/Bi_2WO_6的光催化活性,并解释了复合材料显示较高的可见光催化活性的原因。

Ag3PO4/Bi2WO6 composites were successfully synthesized by precipitation method using Bi2WO6 as carrier. The structure and optical absorption properties of the materials were well characterized by X – ray diffraction patterns and UV – vis diffuse reflectance spectroscopy. Subsequently,their visible photocatalytic activity was evaluated by the degradation Rhodamine B,and explained the reasons for enhanced photocatalytic activity of composite.
