| 英文摘要 | ultra-low pt catalysts with pt(shell)-au(core) nanostructure were prepared by seed mediate method for oxygen reduction reaction (orr). the as-prepared catalysts were characterized by transmission electron microscopy (tem) and uv-vis measurements. the orr activities of the catalysts were studied by electrochemical measurements and single cell tests, respectively. the results indicate that the ptau/c (pt: au = 3:2, pt + au = 4 wt.%) catalyst exhibits the core-shell nanostructure and attractive catalytic activity in both electrochemical test and single cell test. the pt(shell)-au(core) nanostructure is promising for application to lower the cost of pemfcs.
