Ag3PO4形貌对抗菌及光催化性能的影响

摘要

Four kinds of silver phosphates with different morphologies were prepared by facile ion-exchange 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 degradation of RhB rank was:rhombic dodecahedron＞cubic＞sphere＞triangular pyramid.%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.
