Abstract

In this study, we investigated the formation and influence of Ag particles on the physical properties and photocatalytic performance of Ag3PO4 photocatalysts when Ag particles adhered to the Ag3PO4 surface. The material is prepared by a simple precipitation method with illumination. The properties of the materials were investigated by X-ray diffraction (XRD), Raman scattering, scanning electron microscopy (SEM), UV-vis absorption, and the photocatalytic ability to decompose organic solutions. The results show the vibrational change of the [PO4] group in the structure presented in the Raman scattering spectrum highest RhB decomposition. The experimental results indicated that the Ag\Ag3PO4 showed highly efficient and stable photocatalytic activity under visible light irradiation. The Ag\Ag3PO4 sample with the Ag+\PO43- the ratio of 3.6\1 gave efficiency when stimulated with visible light of Xenon lamps. This sample degraded almost completely to RhB in 10 ppm solution after 15 min of illumination, with a decomposition rate of 0.241 min-1.

Ag\Ag3PO4复合材料增强Ag3PO4的光催化活性

在本研究中，我们研究了Ag颗粒附着在Ag3PO4表面时，Ag颗粒的形成及其对Ag3PO4光催化剂物理性能和光催化性能的影响。该材料是用光照下的简单沉淀法制备的。通过x射线衍射(XRD)、拉曼散射(Raman scattering)、扫描电镜(SEM)、紫外可见吸收(UV-vis)以及光催化分解有机溶液的能力对材料的性能进行了研究。结果表明，结构中[PO4]基团的振动变化呈现在喇曼散射光谱最高的RhB分解处。实验结果表明，Ag\Ag3PO4在可见光照射下表现出高效稳定的光催化活性。Ag+\PO43-比值为3.6\1的Ag\Ag3PO4样品在氙灯可见光刺激下具有较高的效率。光照15分钟后，样品在10ppm溶液中几乎完全降解为RhB，分解速率为0.241 min-1。
