| 英文摘要 | in this work, high-surface supported ptru/c were prepared with ru(no)(no3)(3) and [pt(h2nch2ch2nh2)(2)]cl-2 as the precursors and hydrogen as a reducing agent. xrd and tem analyses showed that the ptru/c catalysts with different loadings possessed small and homogeneous metal particles. even at high metal loading (40 wt.% pt, 20 wt.% ru) the mean metal particle size is less than 4 nm. meanwhile, the calculated pt crystalline lattice parameter and pt (220) peak position indicated that the geometric structure of pt was modified by ru atoms. among the prepared catalysts, the lattice parameter of 40-20 wt.% ptru/c contract most. cyclic voltammetry (cv), chronoamperometry (ca), co stripping and single direct methanol fuel cell tests jointly suggested that the 40-20 wt.% ptru/c catalyst has the highest electrochemical activity for methanol oxidation.
