Abstract

In this work, a plasmonic Ag/Ag₃PO₄/Chitosan composite photocatalyst was prepared by a low-temperature strategy. Environmentally friendly chitosan plays triple vital roles in this composite. First, it was devoted to in situ reduce metallic silver from silver ions of Ag₃PO₄. Also, as a carrier of Ag/Ag₃PO₄ nanoparticles, chitosan can effectively prevent aggregation. Furthermore, benefiting from the settlement of hydrophilic chitosan, the prepared composite could be easily separated and recovered from the solution system. X-ray diffraction, scanning electron microscope, energy-dispersive X-ray spectroscopy, UV–visible diffused reflectance spectroscopy and X-ray photoelectron spectroscopy were employed to characterize the properties of materials. The results of photo-decomposition testing showed that the Ag/Ag₃PO₄/Chitosan composite possessed a good activity for the decomposition of Rhodamine B (RhB) under visible light.

Ag/Ag3PO4/壳聚糖复合光催化剂的绿色合成及其可见光下的光催化降解性能

本文采用低温策略制备了等离子体Ag/Ag3PO4/壳聚糖复合光催化剂。环境友好型壳聚糖在这种复合材料中起着三重重要作用。首先，研究了Ag3PO4银离子原位还原金属银的方法。壳聚糖作为Ag/Ag3PO4纳米粒子的载体，可以有效地防止Ag/Ag3PO4的聚集。此外，得益于亲水性壳聚糖的沉降，制备的复合材料易于从溶液体系中分离和回收。利用x射线衍射、扫描电子显微镜、能量色散x射线能谱、紫外-可见漫反射能谱和x射线光电子能谱对材料的性质进行表征。光分解测试结果表明，Ag/Ag3PO4/壳聚糖复合材料在可见光下对罗丹明B (Rhodamine B, RhB)具有良好的分解活性。
