摘要: 通过硝酸银[AgNO3]和磷酸氢二铵[(NH4)2HPO4]在室温条件下发生离子交换反应,合成了粒径约300 nm的纳米磷酸银[Ag3PO4]可见光光催化剂,通过X射线粉末衍射(XRD),扫描电子显微镜(SEM)和紫外可见漫反射光谱(UV-Vis-DRS)对其结构,形态和光学特性进行研究。并以罗丹明B为目标降解染料,研究了pH值、催化剂用量、染色剂和添加剂等对其光催化性能的影响。结果表明,Ag3PO4光催化剂具有较好的可见光催化降解能力,在pH = 3时光催化降解罗丹明B的效率最高。
Abstract: Ag3PO4 nanoparticles of 300 nm were synthesized by an ion-exchange reaction between AgNO3 and (NH4)2HPO4 at ambient condition. X-ray powder diffraction, scanning electron microscopy and UV-Vis diffuse reflectance spectroscopy were employed to investigate the phase structure, mor-phology, and optical property of the Ag3PO4 nanoparticles. The effects of pH value, amount of cat-alyst, coloring agent and additive on the photocatalytic activity of the catalyst were studied. The results showed that the Ag3PO4 photocatalyst had better visible light photocatalytic degradation of Rhodamine B under pH = 3.
