英文摘要: Carbon nanoribbons (CNRs) were synthesized using the resorcinol-formaldehyde gel as a precursor and were characterized by X-ray diffraction, transmission electron microscopy, and nitrogen adsorption-desorption. CNRs are highly graphitized and the width of the ribbon is 8-20 nm. The BET surface area of CNRs is 283 m(2) /g, and the nitrogen isotherm for the CNRs with an average pore size of 8.2 nm is classified as type-IV. A platinum-based binary electrocatalyst, PtRu/CNRs, using CNRs as the support and having a metal loading of 45% was prepared using a modified polyol process. The performance of the single cell using PtRu/CNRs as the anode electrocatalyst is significantly improved when compared with that using Vulcan XC-72R as the support, indicating that CNRs are promising electrocatalyst supports for direct methanol fuel cells.
