The synthesized catalyst is characterized by means of FESEM, XRD, ICP-MS, XPS and \u03bcRS analyses. MnO2 is synthesized and deposited over a commercial grade of carbon (Vulcan XC72) by facile reduction of potassium permanganate in acidic solution. Pt nanoparticles are synthesized on the hybrid support by a polyol thermal assisted method (microwave irradiation), followed by an annealing at 600 \u00b0C. The obtained catalyst displays a support constituted by a mixture of manganese oxides (Mn2O3 and Mn3O4) with a Pt loading of 19 wt. %. The electro-catalytic activity towards MOR is assessed by RDE in acid conditions (0.5 M H2SO4), evaluating the ability to oxidize methanol in 1 M concentration. The synthesized Pt\/C-MnxO1+x catalyst shows good activity as well as good stability compared to the commercial Pt\/C based catalyst.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.3390\/catal5031399<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Alessandro Hugo Monteverde Videla, Luigi Osmieri, Reza Alipour Moghadam Esfahani, Juqin Zeng, Carlotta Francia, Stefania Specchia<\/div>\n<h4>Abstract:<\/h4>\n<div class=\"b-intro\">Platinum (Pt) nanoparticles are deposited on a hybrid support (C-MnO2) according to a polyol method.
