英文摘要	ultrathin ptcux (x=1, 2 and 3) nanowire networks (nwms) with controllable compositions were successfully synthesized by using triton x-100 as the structure-directing agent in aqueous solution. the as-prepared ptcux nanocrystals were characterized by transmission electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy, cyclic voltammetry, and chronoamperometry. the results show that electrocatalytic performance of the ptcux nwns towards the methanol oxidation reaction is enhanced relative to that of commercial pt/c catalysts. moreover, if the initial atomic ratio of pt/cu is 1:2, the corresponding ptcu2 nwns catalyst generates mass activity that is 3.77-fold higher and specific activity that is 2.71-fold higher than the corresponding properties of commercial pt/c catalysts. the enhanced activity can be attributed to a unique structure and a modified electronic effect.
