英文摘要 | in the present investigation, ptrutiox/c electrocatalyst was prepared by a modified polyol synthesis method and the as-prepared electrocatalyst was treated under the reductive atmosphere (30 vol% h-2 in ar) at 500 degrees c for 2 h (denoted as ptrutiox/c-500) to enhance the interaction between the metal particles and the support. for comparison, the commercial ptru/c electrocatalyst was also treated by the same procedure as ptrutiox/c (denoted as ptru/c-500). transmission electron microscopy results indicated that ptrutiox/c electrocatalyst exhibited not only a uniform dispersion and narrow size distribution with a smaller particle size, but also excellent stability during the thermal treatment. in contrast, the commercial ptru/c electrocatalyst is not stable during the thermal treatment and the metal particles greatly agglomerated. the results of co-stripping voltammetry, single direct methanol fuel cell tests and life-time test jointly showed that ptrutiox/c-500 had better durability than commercial ptru/c while keeping a desirable activity toward methanol electro-oxidation, which may be attributed to the addition of titanium oxide that improved the interaction between noble metal particles and the support.
