| 摘 要： | 为提高钛基二氧化锡电极的稳定性,设计并制备了含Co中间层的钛基二氧化锡电催化电极Ti/Co/SnO2,以苯酚为目标有机物,考察了所制备Ti/Co/SnO2电极电催化氧化降解苯酚的性能,并采用SEM、EDX以及XPS等检测方法分析了Ti/Co/SnO2电极表面的形貌、元素组成及元素化学态.研究结果表明,含有中间层的Ti/Co/SnO2电极其使用寿命较不含中间层的钛基二氧化锡电极Ti/SnO2大幅度提高,但其对苯酚的电催化降解活性有所下降,氧化还原电对Co2 /Co3 的存在是所制备Ti/Co/SnO2电极稳定性及电催化活性改变的主要原因.

| Abstract: | Ti-base tin dioxide electrode with an inter-layer containing Co element was prepared by thermal deposition technology. Taking phenol as the model substrate, the electro-catalytic oxidation characteristics of prepared electrode were investigated. The micrograph of the electrode surface, the element composition of different layers and the chemical environment of Sn and Co in the electrode surface were analyzed with the help of SEM, EDX and XPS. It was found that by covering an inter-layer onto the Ti base metal, the service life of the tin dioxide electrode was increased while the electro-catalytic activity on phenol degradation was decreased. The redox couple of Co~(2+)/Co~(3+) was believed to be responsible for long service life and low electro-catalytic activity of the Ti/Co/SnO_2 electrode. |
