Silver orthophosphate (Ag3PO4) has received enormous attention over the past few years for its higher visible light photocatalytic performance as well as for various organic pollutants degradation in aqueous media. Therefore, considerable efforts have been made to the synthesis of Ag3PO4 with high catalytic efficiency, long lifetime, and using low-cost inorganic precursors. This article describes our efforts to develop a novel approach to synthesize of nanostructured silver phosphate (Ag3PO4) using phosphate rock as alternative and natural source of PO43− precursor ions. The catalytic experimental studies showed that the nanostructured Ag3PO4 exhibited excellent catalytic activity for reduction of p-nitrophenol in the presence of NaBH4 at room temperature. Furthermore, the antibacterial studies revealed that the obtained Ag3PO4 possess significant effect against E. Coli and S. Aureus bacteria. The obtained results make the nanostructured Ag3PO4 prepared from natural phosphate as a highly promising candidate to be used as efficient catalyst and antibacterial agent.

从磷矿中合成纳米结构 Ag3PO4 的新方法：高催化和抗菌活性


正磷酸银（Ag3PO4）因其较高的可见光光催化性能以及在水介质中降解各种有机污染物而在过去几年中受到了极大的关注。因此，人们在合成具有高催化效率、长寿命和使用低成本无机前驱体的Ag3PO4方面付出了巨大的努力。本文介绍了我们开发一种新方法来合成纳米结构磷酸银 (Ag3PO4) 的努力，该方法使用磷酸盐岩作为 PO43− 前体离子的替代和天然来源。催化实验研究表明，纳米结构的Ag3PO4在NaBH4存在下在室温下对对硝基苯酚的还原表现出优异的催化活性。此外，抗菌研究表明，所获得的Ag3PO4对大肠杆菌和金黄色葡萄球菌具有显着的作用。所获得的结果使得由天然磷酸盐制备的纳米结构Ag3PO4成为非常有希望用作高效催化剂和抗菌剂的候选者。
