摘要
采用阳极氧化法在钛金属表面制备出致密有序的TiO2纳米管阵列,利用紫外光和电子束辐照沉积技术分别在其上沉积铜纳米颗粒以提高其光电性能.利用场发射扫描电镜观察两种不同技术制备的TiO2纳米管阵列负载纳米铜结构的表面形貌.研究比较了不同制备方法得到的样品在紫外光和可见光照射下的光电效应,并讨论不同浸泡溶液浓度对其光电性能的影响.
Dense and highly ordered titania nanotube arrays(TiNT) were fabricated by electrochemical anodic oxidation.Cu nanoparticles were depositied on the surface of TiNT by UV light and electron beam irradiation,to improve their opto-electronic response.The surface morphology was characterized by scanning electron microscope(SEM).Photoelectric efficiency of samples under UV light and visible light excitation was studied.Influence of Cu(NO3)2 solution concentration on photoelectric efficiency was discussed.
