中文摘要a novel method was developed to prepare the highly active pt-ru-p/c catalyst. the deposition of phosphorus significantly increased electrochemical active surface (eas) area of catalyst by reduces pt-ru particle size. tem images show that pt-ru-p nanoparticles have an uniform size distribution with an average diameter of 2 nm. cyclic voltammetry (cv), chronoamperometry (ca), and co stripping indicate that the presence of non-metal phosphorus as an interstitial species pt-ru-p/c catalyst shows high activity for the electro-oxidation of methanol, and exhibit enhanced performance in the oxidation of carbon monoxide compared with pt-ru/c catalyst. at 30 degrees c and pure oxygen was fed to the cathode, the maximum power density of direct methanol fuel cell (dmfc) with pt-ru-p/c and pt-ru/c catalysts as anode catalysts was 61.5 mw cm(-2) and 36.6 mw cm(-2), respectively. all experimental results indicate that pt-ru-p/c catalyst was the optimum anode catalyst for direct methanol fuel cell.
