Preparation and Characterization of Fe Doped Ti-Based SnO2/Sb Electro-Catalytic Electrode

为了改进钛基SnO2/Sb电极的电催化性能,采用高温热氧化法制备了Fe掺杂钛基SnO2/Sb 电极.采用SEM、EDX以及XRD等方法对所制备电极的表面形貌、元素组成及结构进行分析,并以苯酚为目标有机物,研究了所制备电极对有机污染物的电催化降解能力.结果表明,适量Fe的掺杂有利于晶粒细化和导电性的提高;但过量Fe的掺杂可能导致SnO2晶格的混乱程度增大,甚至使晶格破坏,从而使电极性能降低;掺杂0.5%Fe的SnO2/Sb电极对苯酚的降解效果优于未掺杂Fe的电极;电解3 h后,苯酚去除率和化学需氧量(COD)去除率分别达到100.0%和92.0%.
