| 摘 要： | 应用循环伏安法制备了nano-Pt/GC电极,并用SEM和电极在H2SO4中的循环伏安曲线对其进行了表征。结果表明,该方法制备的电极表面铂粒子分布较为均匀,粒径大小约为140nm,电极具有较大比表面积。电化学实验表明,该电极对甲醛电氧化的催化活性明显好于铂片电极。修饰电极的催化活性与铂粒子的沉积条件有关,铂微粒在电极表面的最佳沉积条件为循环次数100次和沉积速度5mV/s。

| Abstract: | The nano- t/GC electrode was prepared with circlic voltammetry and characterized by SEM and cyclic voltammogram curves in H2SO4 solution. The results were that the platinum particle evenly dispersed on GC electrode surface and the particle size was approximately 140nm. A very big relative surface of electrode was obtained. The electrochemical experiment indicated that catalyzed performance of nano-Pt/GC for the formaldehyde's electrooxidation is better than platinum foil. Catalyzed performance of nano-Pt/GC... |
