Ag_3PO_4形貌对抗菌及光催化性能的影响

Morphology effect of Ag_3PO_4 on antibacterial properties and photocatalytic properties

通过简单的离子交换法制备出4种不同形貌的磷酸银,利用XRD、SEM、FT-IR等分别对4种样品的晶相、微观形貌和结构等进行了表征。测定了4种形貌磷酸银的抗菌性和光催化性能,结果表明,抗菌能力排序:立方体>菱形十二面体>三棱锥>球形;光催化降解罗丹明B的能力排序:菱形十二面体>立方体>球形>三棱锥。

Four kinds of silver phosphates with different morphologies were prepared by facile ion-ex-change method. XRD, SEM and FT-IR were used to characterize their phase, morphology and structure. The antimicrobial properties and photocatalytic performance were characterized. The results showed that the antibacterial capacity rank was： cubic〉rhombic dodecahedron〉triangular pyramid〉sphere. The photocatalytic degra-dation of RhB rank was： rhombic dodecahedron〉cubic〉sphere〉triangular pyramid.
