摘要
采用金属有机化学气相沉积技术制备了SnO2 修饰碳纤维微柱电极 ,讨论了电极的表面结构和稳定性 ,并利用循环伏安法分析了酚类化合物在电极上的电化学行为。该电极对酚类化合物有明显的电催化活性 ,并能防止酚类物质在碳纤维电极表面的电聚合。以 3 氯苯酚为测试物 ,其检测的线性浓度范围为 2× 10 -6～ 1.2× 10
A stannic oxide modified microcyclinder carbon fiber(SnO2/C) electrode was constructed using organic chemical vapor deposition technique. The surface morphology and stability of C/SnO2 electrode were discussed and the electrochemical behavior of phenols on the electrode was studied by cyclic voltammetry. The electrode shows significant electrocatalytic activity to the oxidation of phenols and prevents the electrochemical polymerization of phenols on it. The amperometric response to 3-chlorophenol increases linearly with increasing concentration from 2 x 10(-6) to 1.2 x 10(-5) mol/L.
