中文摘要	a modified impregnation method was used to prepare highly dispersive carbon-supported ptru catalyst (ptru/c). two modifications to the conventional impregnation method were performed: one was to precipitate the precursors ((nh4)(2)ptcl6 and ru(oh)(3)) on the carbon support before metal reduction: the other was to add a buffer into the synthetic solution to stabilize the ph. the prepared catalyst showed a much higher activity for methanol electro-oxidation than a catalyst prepared by the conventional impregnation method. even higher than that of current commercially available, state-of-the-art catalysts. the morphology of the prepared catalyst was characterized using tem and xrd measurements to determine particle sizes, alloying degree, and lattice parameters. electrochemical methods were also used to ascertain the electrochemical active surface area and the specific activity of the catalyst.
