| 摘 要： | 以负载FeSalen(Salen=N,N-双水杨醛缩乙二胺)配合物的APO-5磷铝分子筛复合材料(FeSalen/APO-5)做电极的修饰主剂,聚苯乙烯(PS)为粘结剂,采用物理吸附法在玻碳电极(GCE)表面形成涂层,制备获得FeSalen修饰的玻碳电极(PS/FeSalen/APO-5/GCE)。采用循环伏安法(CV)研究了此修饰电极在不同pH电解液中的电化学性质及其对氧还原反应的电催化作用。结果表明,氧气的电催化还原峰电流随扫描速率的增大而增强,峰电位随扫描速率的增大而负移,ipc~v1/2和Epc~lnv均呈线性关系,并发现此修饰电极能有效地催化分子氧的四电子还原反应,推断其机理属于ECE催化过程。 |
| 关 键 词： | 修饰电极 电催化 氧还原 循环伏安法 |

| Abstract: | A FeSalen/APO-5 modified electrode was prepared by coating the suspension of tetrahydrofuran containing FeSalen/APO-5,pure graphite and polystyrene(PS) on the surface of glassy carbon electrode.The modified electrode showed a stable electrochemical reaction of FeSalen at about 0.05V(vs SCE). The electrochemical behaviors and the electrocatalysis for dioxygen reduction were studied by cyclic voltammetry at PS/FeSalen/APO-5/GC modified electrode in various pH aqueous solutions.The results show that the peak c... |
