我们报道了通过简单的溶液沉淀反应可控制备Ag 3 PO 4纳米/微米晶体。采用X射线粉末衍射、扫描电子显微镜、透射电子显微镜和红外光谱对样品进行了表征。结果表明，在水、乙二醇（EG）和二甲基亚砜（DMSO）溶剂中，可以得到尺寸为500 nm的菱形十二面体、100 nm的球形和20 nm的小颗粒三种不同形貌的Ag 3 PO 4晶体。抑菌实验表明，所有样品均具有明显的抗菌性能。此外，粒径较小（20 nm）的Ag 3 PO 4由于具有较高的比表面积而表现出较好的催化活性。在可见光照射下，Ag 3 PO 4的抗菌能力明显提高，比在黑暗条件下的抗菌能力和市售链霉素的抗菌能力有上级提高。(C)2013爱思唯尔有限公司保留所有权利。
We reported the controllable fabrication of Ag3PO4 nano/microcrystals through a simple solution-based precipitation reaction. The samples were characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy and infrared spectroscopy. The results indicated that the Ag3PO4 crystals with three different morphology, including the rhombic dodecahedron of 500 nm, the sphere of 100 nm and the particles with small-size of 20 nm, could be obtained in the solvents of water, ethylene glycol (EG) and dimethyl sulfoxide (DMSO). The antibacterial assay showed that all samples possess obvious antibacterial properties. In addition, the Ag3PO4 with small size of 20 nm showed better activity due to their high specific surface areas. Notably, we have found that the antibacterial ability of Ag3PO4 could be greatly improved under the visible light irradiation, which are superior to that in the dark and commercial streptomycin.
