摘要
室温下,以ZnO粉体、Na_2HPO_4、Ag NO_3和聚乙烯吡咯烷酮为原料,成功制备出了系列Ag_3PO_4/ZnO复合粉体。采用X射线衍射仪、扫描电子显微镜和紫外-可见光谱仪分别对复合粉体的物相、形貌和可见光吸收性能进行了表征。研究了不同摩尔比的Ag_3PO_4/ZnO复合粉体的光催化性能。结果表明:当ZnO和Ag_3PO_4摩尔比约为1:1时,所得的Ag_3PO_4/ZnO复合粉体对罗丹明B染料的可见光催化效果最好,降解率达到99%。
Using ZnO powders,Na2HPO4,Ag NO3 and polyvinylpyrrolidone as raw materials,Ag3PO4/ZnO composite powders were successfully prepared at room temperature. The phase structure,morphology and adsorption of visible-light of composites with various ratios of ZnO and Ag3PO4 were characterized by X ray diffraction,scanning electron microscopy and UV spectrometer. The photocatalytic activity of corresponding Ag3PO4/ZnO composite powders was also investigated. The results show that the performance of photocatalytic degradation of rhodamine B is excellent（ the degradation rate is 99% or so）when the molar ratio of ZnO and Ag3PO4 is about 1：1.
