Abstract:
TiO2 nanotube arrays (TNTs) electrode loaded with Zn nanoparticles was prepared by anodization and the size of Zn nanoparticle loaded on TNTs electrode was controlled by chronoamperometry deposition time. Results of SEM and XRD analysis show that Zn nanoparticles had a diameter of about 15-25 nm when the deposition time was 3-5 s. The UV-Vis diffuse reflectance spectra show the Zn loaded harvest light with 480-780 nm more effectively than the unloaded sample. The photocurrent response of Zn loaded TNTs electrodes were studied, the results showed that TNTs electrodes loaded with Zn nanoparti-cles has 50% increased photocurrent response under high-pressure mercury lamp irradiation compared with unloaded TNTs electrode.

摘要:
采用计时电流法制备了负载Zn纳米粒子的TiO2纳米管阵列电极.通过阳极氧化法制备TiO2纳米管阵列电极,然后通过控制计时电流沉积时间来控制负载在TiO2纳米管上Zn纳米颗粒的沉积量和 沉积尺寸.SEM和XRD分析结果显示,沉积时间为3~5 s时,负载在TiO2纳米管上的Zn粒子的直径为15~25 nm.UV漫反射光谱发现负载Zn的TiO2纳米管阵列电极比没有负载的样品吸收487~780 nm的光更强;在高压汞灯照射下,前者比后者的光电流响应提高了50%.
