Abstract

Background

Trichloroethylene (TCE) is harmful to the ecosystem and difficult to remove. Therefore, it is necessary to develop an environmentally friendly and efficient technology for TCE removal.

Method

In this study, iron-modified titanate nanotube arrays (Fe-TNAs) was synthesized by square wave voltammetry electrodeposition method (SWVE) for the first time. The surface property of Fe-TNAs was characterized by Cold Field Emission Scanning Electron Microscope (FE-SEM), Ultraviolet-Visible Diffuse Reflectance Spectroscopy (UV-vis DRS), X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and Photoluminescence Spectroscopy (PL). The photoelectrocatalytic performance of Fe-TNAs was measured by photocurrent, Electrochemical Impedance Spectroscopy (EIS), and Mott-Schottky (M-S). Fe-TNAs was employed as photoelectrode in PEC system to remove TCE.

Significant Findings

The morphology, crystal structure, element state, and optics of Fe-TNAs had been characterized. Moreover, the PEC performance of Fe-TNAs was significantly enhanced after iron modification. In TCE removal experiments, PEC-Fe- TNAs process was the best way to remove TCE, which was attributed to the modification of iron and synergistic effect of photocatalysis (PC) and electrocatalysis (EC). The mechanism and pathway of TCE removal by the PEC-Fe-TNAs process were proposed in detail to clarify the redox reaction.

铁修饰钛酸盐纳米管阵列光电极用于优越的光电催化去除三氯乙烯

背景三氯乙烯（TCE）对生态系统有害且难以去除。因此，有必要开发一种环境友好、高效的TCE去除技术。方法首次采用方波伏安电沉积法（SWVE）合成铁修饰钛酸盐纳米管阵列（Fe-TNAs）。采用冷场发射扫描电镜（FE-SEM）、紫外-可见漫反射光谱（UV-vis DRS）、x射线衍射（XRD）、x射线光电子能谱（XPS）和光致发光光谱（PL）对fe - tna的表面性质进行了表征。采用光电流、电化学阻抗谱（EIS）和Mott-Schottky （M-S）测试了fe - tna的光电催化性能。采用fe - tna作为光电极在PEC系统中去除TCE。研究了fe - tna的形貌、晶体结构、元素态和光学性质。铁改性后，fe - tna的PEC性能显著提高。在TCE的去除实验中，PEC-Fe- tna工艺是去除TCE的最佳方法，这主要归功于铁的改性以及光催化（PC）和电催化（EC）的协同作用。详细介绍了pec - fe - tna工艺去除TCE的机理和途径，阐明了氧化还原反应。
