汞离子光电化学传感器工作电极及其制备方法和应用
摘要：
本发明公开了汞离子光电化学传感器工作电极及其制备方法和应用，属于化学分析检测技术领域。本发明光电化学传感器工作电极首先由二氧化钛纳米线在FTO导电玻璃上水热合成氨基化的二氧化钛纳米线；然后将光敏分子与氨基化的二氧化钛纳米线通过化学键合偶联得到。该传感器工作电极对汞离子的具有高选择性和高灵敏度的优点，且响应速度快，响应范围为0.5 nmol·L?1 – 50 μmol·L?1，检测限达到0.15 nmol·L?1。增强了汞离子光电化学传感器对汞离子识别的精确控制，且光敏染料分子结构稳定有利于维持传感器稳定性，具有很好的开发前景。

The manufacturing method of the photo-electrochemical sensor working electrode comprises the following steps: performing hydro-thermal synthesis on titanium dioxide nanowires on FTO conductive glass to form amination titanium dioxide nanowires; coupling photosensitive molecules with the amination titanium dioxide nanowires through chemical bonding to obtain the working electrode. The sensor working electrode has the advantages of high selectivity and high sensitivity to mercury ions, the response speed is high, the response range is 0.5nmol.L<-1>-50mumol.L<-1>, and the detection limit is up to 0.15nmol.L<-1>. Accurate control on mercury ion recognition by a mercury ion photo-electrochemical sensor is enhanced, a stable photosensitive dye molecular structure contributes to keeping of sensor stability, and the working electrode has a good development prospect.
