制备了一种新型钛基纳米电极以提高电化学硝酸盐还原效率。扫描电子显微镜（SEM）和X射线光电子能谱（XPS）结果表明，钛基纳米电极表面覆盖有大量纳米粒子，且具有相对均匀的管状结构，电极的主要成分为TiO2。钛基纳米电极的循环伏安（CV）分析结果表明，与钛电极相比，其电化学活性有所增强。结果发现，使用钛基纳米电极作为阴极和Ti/Pt阳极，通过电化学方法可以有效去除硝酸盐。所开发的系统能够在一系列实验条件下促进硝酸盐的电化学还原。研究发现，氯化钠的添加对副产物的去除有积极的影响，因此与硝酸盐还原相结合，达到了清洁、安全去除污染物的目的。
A novel Ti-based nano-electrode was fabricated to improve electrochemical nitrate reduction efficiency. The results of scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) demonstrated that the surface of the Ti-based nano-electrode was covered with a large number of nanoparticles, as well as relatively homogenous tubular structure, and that the main component of the electrode was TiO2. Cyclic voltammetry (CV) analysis of Ti-based nano electrode result indicated that it was capable of enhanced electrochemical activity in comparison with Ti electrode. It was found that nitrate was removed efficiently by electrochemical means using the Ti-based nano-electrode as cathode with a Ti/Pt anode. The developed system was able to promote the electrochemical reduction of nitrate under a range of experimental conditions. The addition of NaCl was found to positively affect the removal of by-products, and thus, in combination with nitrate reduction, achieved the goal of clean, safe removal of pollutants.
