C-PANI/Ag/Ag3PO4复合材料增强可见光光催化性能
Preparation of C-PANI/Ag/Ag3PO4 with Enhanced Visible Light Photocatalytic Activity
摘要
Abstract
A carbon nanowire material (C-PANI) was prepared using polyaniline (PANI) via high-temperature calcination, and then a series of C-PANI/Ag/Ag3PO4compound materials were synthesized by a deposition method.Crystal structure, microstructure and element distribution of these compound materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and SEM elemental mapping technologies. The optical absorption properties of the prepared samples were measured with UV spectrophotometer (UV-VIS), and the visible light degradation performance of these samples was investigated. The results show that the visible light photocatalytic performance of the C-PANI/Ag/Ag3PO4 compound materials is significantly enhanced compared with pure Ag3PO4, which is due to successful loading of Ag/Ag3PO4onto C-PANI surface and formation of effective contact with C-PANI. 25%(wt) C-PANI/Ag/Ag3PO4 can completely degrade RhB in 10 minutes with visible light irradiation, and the photocatalytic activity is 3.5 times of that of pure Ag3PO4. Moreover, C-PANI can provide more active sites for the reaction of Ag3PO4. The improved photocatalytic activity is attributed to the effective separation of the photogenerated electrons and holes, in which C-PANIserves as the receptor of photogenerated electrons.关键词
