摘要:

本工作通过两步合成法制备了WO3颗粒修饰的TiO2纳米管阵列光电极。首先通过电化学氧化法制备得到TiO2纳米管阵列,接着通过改变电沉积氧化钨的时长(1,2,3,5和20 min),以此提高光电极的光电催化性能及产氢量。本工作运用了多种表征方式。通过能量色散X射线光谱仪(EDX)确认W元素存在于改性的TiO2纳米管阵列。场发射扫描电镜(FESEM)和高分辨透射电镜(HRTEM)证实在较短的电沉积条件下,氧化钨以微小颗粒的形貌堆积于纳米管表面,而当电沉积时间较长时,氧化钨颗粒聚集形成大颗粒并堵塞纳米管。此外,由紫外-可见漫反射光谱可以证实,经WO3修饰后,光电极的吸收带边出现红移,这表明光电极的禁带宽度减小。因此,经修饰的TiO2纳米管阵列可以更加有效的吸收太阳能,因而更加高效的制备氢气。根据实验数据可知,电沉积2 min的光电极性能最佳,其产氢效率较纯TiO2纳米管阵列提高了30%。

Abstract

WO3 decorated photoelectrodes of titanium nanotube arrays (W-oxide TNTAs) were synthesized via a two-step process, namely, electrochemical oxidation of titanium foil and electrodeposition of W-oxide for various interval times of 1, 2, 3, 5, and 20 min to improve the photoelectrochemical performance and the amount of hydrogen generated. The synthesized photoelectrodes were characterized by various characterization techniques. The presence of tungsten in the modified TNTAs was confirmed using energy dispersive X-ray spectroscopy (EDX). Field emission scanning electron microscopy (FESEM) and high resolution transmission electron microscope (HRTEM) proved the deposition of W-oxide as small particles staked up on the surface of the tubes at lower deposition time whereas longer times produced large and aggregate particles to mostly cover the surface of TiO2 nanotubes. Additionally, the incorporation of WO3 resulted in a shift of the absorption edge toward visible light as confirmed by UV-Vis diffuse reflectance spectroscopy and a decrease in the estimated band gap energy values hence, modified TNTAs facilitated a more efficient utilization of solar light for water splitting. From the photoelectrochemical measurement data, the optimal photoelectrode produced after 2 min of deposition time improved the photo conversion efficiency and the hydrogen generation by 30% compared to that of the pure TNTA.
