Silver orthophosphate (AgPO) 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 AgPO 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 (AgPO) using phosphate rock as alternative and natural source of PO precursor ions. The catalytic experimental studies showed that the nanostructured AgPO exhibited excellent catalytic activity for reduction of p-nitrophenol in the presence of NaBH at room temperature. Furthermore, the antibacterial studies revealed that the obtained AgPO possess significant effect against E. Coli and S. Aureus bacteria.
The obtained results make the nanostructured AgPO prepared from natural phosphate as a highly promising candidate to be used as efficient catalyst and antibacterial agent.
在过去几年中，正磷酸银（AgPO）因其较高的可见光光催化性能以及在水介质中对各种有机污染物的降解能力而受到广泛关注。因此，人们为合成具有高催化效率、长寿命且使用低成本无机前驱体的AgPO做出了相当大的努力。
本文描述了我们开发一种新方法的努力，该方法使用磷矿石作为PO前驱体离子的替代天然来源来合成纳米结构的磷酸银（AgPO）。催化实验研究表明，纳米结构的AgPO在室温下于NaBH存在时对还原对硝基苯酚表现出优异的催化活性。此外，抗菌研究表明，所获得的AgPO对大肠杆菌和金黄色葡萄球菌具有显著的抗菌效果。
所获得的结果使由天然磷酸盐制备的纳米结构AgPO成为用作高效催化剂和抗菌剂的极具潜力的候选材料。
