| 摘 要： | 采用金属离子氯化盐溶胶热分解法制备了Fe3 或In3 掺杂的SnO2:Sb5 电极,并通过线性电位扫描法考察了这种电极材料对甲硫氨酸的电催化氧化性能.根据甲硫氨酸在不同掺杂含量的SnO2:Sb5 (5%)-Fe3 和SnO2:Sb5 (5%)-In3 电极上的电催化氧化情况,确定了Fe3 和In3 离子的最佳掺杂含量分别为0.5%和0.3%.根据扫描速度、甲硫氨酸浓度和转速对甲硫氨酸在Fe3 或In3 掺杂的SnO2:Sb5 电极上的电催化氧化的影响结果可以看出,该电极对甲硫氨酸的电催化氧化性能正比于实验所采用的扫描速度、甲硫氨酸的浓度以及旋转圆盘电极的转速.

| Abstract: | SnO2:Sb5+ electrodes co-doped with Fe3+ or In3+ were prepared by thermal decomposition method from the chloride sol,and the activity of these electrodes to electrocatalytic oxidation of methionine was investigated by linear scanning voltammetry.The maximum activity for the anodic oxidation of methionine was found at SnO2:Sb5+(5%)-Fe3+(0.5%) or SnO2:Sb5+(5%)-In3+(0.3%) by comparing different doped quantity of Fe3+ or In3+.Moreover,the electrocatalytic activity of SnO2:Sb5+(5%)-Fe3+ and SnO2:Sb5+(5%)-In3+ electrodes for methionine are proportional to the scan rates,different concentrations of methionine,and different rotating rates of rotation disk electrodes. |
