摘要

摘要:以硒线为模板，采用液相沉积法制备中空硒化铅（PbSe）纳米管，通过光化学还原法在其表面沉积银（Ag）纳米颗粒，获得Ag/PbSe复合纳米管。利用扫描电镜（SEM）、能谱仪（EDS）和Ｘ射线衍射仪（XRD）等对样品的形貌、成分和结构进行表征，测试结果表明，Ag纳米颗粒均匀分布在PbSe纳米管表面，且Ag/PbSe复合材料仍然保持管状结构。通过降解孔雀石绿溶液对Ag/PbSe纳米管的光催化性能进行研究，实验结果表明Ag修饰后的 PbSe 纳米管对孔雀石绿去除效率达到91.8%，且经过4次循环测试，去除率仅下降 5.1% ，说明所制备的Ag/PbSe复合纳米管具有良好的光催化性能和循环稳定性。

Abstract

Abstract:The Ag nanoparticles (NPs) have been deposited ontothe surface of PbSe nanotubes (NTs) via a simple photochemical method at roomtemperatureThe morphology

composition and crystalstructure of the Ag/PbSe NTs have been characterized by scanning electronmicroscope

energy dispersive spectroscope and Xray diffraction The resultsshow that Ag NPs are uniformity dispersed on the PbSe NTs surface Importantly

compared to PbSe NTs

the Ag/PbSe NTs show enhancement of photocatalytic activityin degradation of Malachite Green Furthermore

the photocatalytic circulationexperiments demonstrate the high stability of Ag/PbSe NTs
