| 英文摘要 | Ptru/c nanocatalysts with different size were prepared simply by adjusting the ph of beta-d-glucose solution. herein, beta-d-glucose acts as a reducing agent as well as a capping agent. transmission electron microscopy revealed that the well dispersed ptru particles (12.7, 5.6, and 2.3 nm) were obtained at ph 8.5, 10.5, and 12.5, respectively. x-ray diffraction analysis indicated that the ptru/c catalysts have different structures synthesized at different ph values. only at ph 12.5, small amount of ptru alloy was formed. x-ray photoelectron spectroscopy measurements showed that a large amount of pt and ru were present in metallic states. both cyclic voltammetry and chronoamperometric results demonstrated that the ptru/c catalyst prepared from the solution at ph 12.5 exhibited better performances for methanol electro-oxidation than the other samples.
