摘要

本研究旨在考察低成本阳极氧化法制备TiO2纳米管排列阵列(tna)的工艺参数对其形貌和光催化活性的影响。电解质组成、阳极氧化时间以及外加电压对tna形貌和结构性能的影响包括;长度,内径和壁厚进行了精确的研究。进一步研究了热处理对不同退火温度下样品结晶和相变的影响。研究了制备的样品在紫外光照射下降解对硝基酚的光催化性能。利用场发射扫描电镜(FE-SEM)、能量色散x射线能谱(EDX)和x射线衍射(XRD)等技术观察了光阳极的物理/化学特性。对硝基苯酚的最大光催化性能约为80%。

A Comprehensive Study on Synthesis Parameters of TiO2 Nanotube Arrays: The Effects on Morphology and Photocatalytic Degradation of Para-NitroPhenol
The present research aimed to evaluate the effects of synthesis parameters on morphology and photocatalytic activity of TiO2 nanotube aligned arrays (TNAs) via a low cost anodization process. The impact of electrolyte composition, anodization time, as well as applied voltage on morphological and architecture properties of TNAs including; length, inner diameter, and wall thickness were accurately investigated. We further studied effect of heat treatment on crystalline and phase transformation of the samples at different annealing temperatures. Photocatalytic properties of the fabricated samples were studied for degradation of p-nitrophenol under UV light irradiation. Physical/chemical characteristics of the photo-anodes were observed using several techniques including field emission scanning electron microscopy (FE-SEM) , Energy Dispersive X-Ray Spectroscopy (EDX) and XRD . Moreover, the maximum photocatalytic performance for p-nitrophenol degradation was obtained as about 80%.
