摘要

碳 nanotubes (CNT ) 支持了 Pt-Ru， Pt-Ru-Ni 催化剂被金属先锋的化学减小在室温与钠氢硼化钠准备。催化剂的结晶的性质和作文被X射线衍射描绘( XR ，氘的符号)并且精力为甲醇电镀物品氧化的散X光检查( EDX )分析，和催化活和稳定性被电气化学的阻抗光谱学( EIS )测量，线性打扫 voltammetries ( LSV )，并且 chronoamperometry (20号元素钙的化学符号)。催化剂展出的结果表演以脸为中心立方(费用) 结构。Pt-R.u-Ni/CNTs 催化剂的粒子大小是大约 4.8 nm。Pt-Ru-Ni/CNTs 催化剂的催化活和稳定性比 Pt-Ru/CNTs 催化剂的那些高。给词调音：碳 nanotubes；Pt-Ru-Ni/CNTs；甲醇电镀物品氧化；

The crystallographic properties and composition of the catalysts were characterized by X-ray diffraction (XRD) and energy dispersive X-ray (EDX) analysis, and the catalytic activity and stability for methanol electro-oxidation were measured by electrochemical impedance spectroscopy (EIS), linear sweep voltammetries (LSV), and chronoamperometry (CA). The results show that the catalysts exhibit face-centered cubic (fcc) structure.The particle size of Pt-Ru-Ni/CNTs catalyst is about 4.8 nm. The catalytic activity and stability of the Pt-Ru-Ni/CNTs catalyst are higher than those of Pt-Ru/CNTs catalyst.
