磷酸银-氧化锌复合光催化材料性能的研究

Study on the performance of silver phosphate Zinc oxide composite photocatalytic materials

采用固相反应法将磷酸银与氧化锌结合,制备出磷酸银-氧化锌复合光催化材料,利用X-射线粉末衍射(XRD)、场发射扫描电镜(FESEM)及紫外-可见漫反射光谱(UV-vis)、光电子能谱仪(XPS)等分析测试手段对所得产物进行表征,在可见光(λ>420 nm)照射下,以水中的罗丹明B作为降解对象,采用所合成的磷酸银-氧化锌复合材料作为光催化剂,考察合成产品的光催化性能。

The silver phosphate-Zinc Oxide composite photocatalytic material was prepared by combining silver phosphate with Zinc Oxide by a solid state reaction method.The product was characterized by X-ray powder diffraction( XRD),field emission scanning electron microscopy( FESEM) and ultraviolet-visible diffuse reflectance spectroscopy( UV-vis),photoelectron spectroscopy( XPS). Under the irradiation of visible light(λ> 420 nm),rhodamine B in water was used as the degradation target,and the synthesized silver phosphate-Zinc Oxide composite was used as the photocatalyst to investigate the photocatalytic performance of the synthesized product.
