英文摘要	monodispersed bimetallic pdag nanoparticles can be fabricated through the emulsion-assisted ethylene glycol (eg) ternary system. different compositions of bimetallic pdag nanoparticles, pd80ag20, pd65ag35 and pd46ag54 can be obtained via adjusting the reaction parameters. for the formation process of the bimetallic pdag nanoparticles, there have two-stage growth processes: firstly, nucleation and growth of the primary nanoclusters; secondly, formation of the secondary nanoparticles with the size-selection and relax process via the coalescence or aggregation of the primary nanoclusters. the as-prepared pdag can be supported on the carbon black without any post-treatment, which exhibited high electro-oxidation activity towards methanol oxidation under alkaline media. more importantly, carbon-supported pd80ag20 nanoparticles reveal distinctly superior activities for the methanol oxidation, even if compared with commercial pt/c electro-catalyst. it is concluded that the enhanced activity is dependant on the unique twinning structure with heterogeneous phase due to the dominating coalescence growth in eg ternary system.
