| 中文摘要 | in this paper, it was reported that the carbon-supported pt-ru(pt-ru/c) catalyst used as the anodic catalyst in the direct methanol fuel cell (dmfc) was synthesized with a two-step spray pyrolysis (sp) method using the pt and ru metal salt as the precursors and polyethylene glycol (peg) with the different molecular weights (mw= 200,600,and 1000 analytical reagent) as cosolvent. peg as a cosolvent plays a crucial role in producing ptru/c catalysts. it was found that the mw of peg could affect the electrocatalytic activity of pt-ru and the morphology of the pt-ru particles in the pt-ru/c catalysts prepared with this method. when the mw of peg is 600, the pt-ru particles in the pt-ru/c catalyst prepared with this method possess the small average size, narrow size distribution, uniform dispersion, and high electrochemically active specific surface area. the electrocatalytic activity of the pt-ru/c catalyst prepared with this method using the cosolvent peg with mw = 600 for the methanol oxidation is much higher than that of the commercial e-tek pt-ru/c catalyst. therefore, the two-step sp method is an excellent method for the preparation of the pt-ru/c catalyst used in dmfcs. |
