| 摘 要： | 采用在乙二醇溶液中添加十二烷基硫酸钠(SDS)作为稳定剂的调变乙二醇还原法,制备了高分散的碳纳米管(CNTs)负载Pt电催化剂Pt/CNTs.利用紫外-可见(UV-Vis)、傅里叶变换红外(FTIR)和X射线衍射(XRD)光谱研究了催化剂的制备过程和结构,考察了Pt/CNTs制备过程中SDS的添加对其结构和甲醇电催化氧化活性的影响.结果表明,在乙二醇溶液中PtCl2-6与SDS形成了配合物,PtCl2-6能够被乙二醇完全还原;超声处理后的CNTs表面接上了含氧基团,有利于Pt粒子的吸附,催化剂上不残留有SDS;Pt/CNTs电催化剂具有典型的面心立方结构,添加SDS制备的Pt/CNTs-2电催化剂Pt高度分散,粒径更小,达4.5 nm.循环伏安(CV)测试结果表明,添加SDS制备的Pt/CNTS-2电催化剂比传统乙二醇还原法制备的Pt/CNTs-1具有更高的甲醇电催化氧化活性.

| Abstract: | Carbon nanotubes(CNTs) supported platinum electrocatalyst Pt/CNTs with high dispersion were prepared by a modified ethylene glycol method with sodium dodecyl sulfate(SDS) as the stabilizer.UV-Vis,FTIR and XRD spectroscopic analysis methods were used to study the preparation of the electrocatalysts,and the effect of the SDS addition to the ethylene glycol solution on the structure as well as the electrocatalytic activity of the Pt/CNTs electrocatalysts were also investigated.The results showed that PtCl2-6 c... |
