Pt@ PPy-PANI NPs have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). All the results show that highly crystalline and stable colloidal Pt@ PPy-PANI NPs have been formed as one of the most active and long-lived catalysts with superior reusability performance for the electro-oxidation of methanol at room temperature. Compared to PPy or PANI supported Pt nanoparticles, Pt@ PPy-PANI NPs exhibit extraordinary electrocatalytic activity and stability toward the electro-oxidation of methanol, showing their potential use as a new electrode material for direct methanol fuel cells (DMFCs). It should be primarily attributed to the PPy-PANI, which not only provided larger surface area and flaws for the deposition of Pt nanoparticles, but also the adsorption of more methanol molecules for further oxidation.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/59161</dc:identifier> <dc:identifier>oai:zenodo.org:59161</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>RSC ADVANCES 6(56) 50851-50857</dc:source> <dc:title>Enhanced electrocatalytic activity and durability of highly monodisperse Pt@PPy-PANI nanocomposites as a novel catalyst for the electro-oxidation of methanol</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
