| 内容記述 | In situ high energy resolution fluorescence detection x-ray absorption spectroscopy (HERFD-XAS) was used to evaluate systematically the interactions of H2O and O2 adsorbed on Pt and Pt3Co nanoparticle catalysts in different sizes. The systematic increase in oxidation due to adsorption of different species (H2O adsorption < O2 adsorption < O2 + H2O coadsorption) suggests that cooperative behavior between O2 and H2O adsorptions is responsible for the overpotential induced by hydrated species in fuel cells. | |||||
