金属前驱体对质子交换膜燃料电池用PtCu/C催化剂性能的影响
Influence of metal precursor on the performance of PtCu/C catalyst for proton exchange membrane fuel cell
摘要
Abstract
A series of PtCu/C catalysts ( with a CuPd loading of 20%) were prepared by ethylene glycol ( EG) reduction method with different metal precursors, viz. , CuSO4/CuCl2 and K2 PtCl4/H2 PtCl6 . The morphology, structure and electrochemical performance of as-prepared PtCu/C catalysts were characterized by high-resolution transmission electron microscopy ( TEM) , X-ray diffraction ( XRD) , cyclic voltammetry ( CV) and liner sweep voltammetry ( LSV) techniques. The results indicate that the PtCu/C catalyst prepared with CuSO4 and K2 PtCl4 as precursors exhibit highest electrochemical performance, in which metal particles with a mean size of 2. 3 nm are uniformly dispersed on the carbon support. Such a PtCu/C catalyst has an electro-chemical surface area (ECSA) of 73. 0 m2/gPt and a mass activity (MA) of 126 mA/mgPt, both higher than the commercial Pt/C catalyst.关键词
