Supported 3-D Pt nanostructures: the straightforward synthesis and enhanced electrochemical performance for methanol oxidation in an acidic medium. Journal of Nanoparticle Research, 15: 19591388-0764http://dx.doi.org/10.1007/s11051-013-1959-9http://hdl.handle.net/10566/3432Noble metal nanostructures with branched morphologies [i.e., 3-D Pt nanoflowers (NFs)] by tridimensionally integrating onto conductive carbon materials are proved to be an efficient and durable electrocatalysts for methanol oxidation. The well-supported 3-D Pt NFs are readily achieved by an efficient cobalt-induced/carbon-mediated galvanic reaction approach. Due to the favorable nanostructures (3-D Pt configuration allowing a facile mass transfer) and supporting effects (including framework stabilization, spatially separate feature, and improved charge transport effects), these 3-D Pt NFs manifest much higher electrocatalytic activity and stability toward methanol oxidation than that of the commercial Pt/C and Pt-based electrocatalysts.enThis is the author-version of the article published online at: http://dx.doi.org/10.1007/s11051-013-1959-9NanoflowersBranched morphologiesSupported electrocatalystMethanol oxidationFuel cellsArticle
