摘　　要：以电化学阳极氧化法制备的Ti O2纳米管阵列为基底,分别通过电化学沉积法、化学还原法和浸渍法制备出Ag修饰的Ti O2纳米管阵列,采用XRD、FESEM和UV-Vis等测试手段对样品的组成、结构及形貌等进行表征。以气相苯为降解物,对样品进行光催化活性测试。结果表明:与其他两种方法相比,化学还原法使得Ag纳米颗粒均匀分布在Ti O2纳米管阵列的表面,并表现出更好的光催化降解气相苯的能力。Using Ti O2 nanotube arrays（ TNTs） prepared by electrochemical anodic oxidation as substrates,Ag-modified TNTs were prepared by the electrochemical deposition,chemical reduction and impregnation,respectively. The phase composition, structure and morphology of the samples were characterized by XRD,FESEM and UV-Vis tests. The photocatalytic activity of the samples was tested by degradation of gaseous benzene. The results show that, compared to the other two methods, Ag nanoparticles are uniformly distributed upon the surface of the TNTs by the chemical reduction,and the Ag-modified TNTs have better photocatalytic degradation of gaseous benzene.
