微乳法合成Pt/C、PtIr/C催化剂及其电化学性能表征
Microemulsion Preparation and Electrochemical Characterization of Pt/C,PtIr/C Electrocatalysts
摘要
Abstract
The Pt/C electrocatalysts were prepared by three different systems and the PtIr/C electrocatalysts were prepared with four different Ir contents.The samples were characterized by X-ray diffraction（XRD）,transmission electron microscope（TEM）,cyclic voltammetry（CV）,potentiostatic and potentiodynamic polarizations measurements.The experimental results confirmed that the electrocatalyst particles prepared by the microemulsion method were well distributed on XC-72R supports with the active particle sizes of 5~10 nm and good electrocatalysts activity.The Pt85Ir15/C electrocatalysts showed the highest overall electrochemical activity in unitized regenerative fuel cell.关键词
