Nitrogen-doped carbon coated ZrO2 as a support for Pt nanoparticles in the oxygen reduction reaction. International Journal of Hydrogen Energy, 38: 5783 – 57880360-3199http://dx.doi.org/10.1016/j.ijhydene.2013.03.041http://hdl.handle.net/10566/3508A new nitrogen-doped carbon (CNx) support for Pt electrocatalysts was prepared by carbonizing polypyrrole on the surface of ZrO2 (ZrO2@CNx) at high temperature. Well-dispersed Pt nanoparticles were easily formed on the ZrO2@CNx. The electrocatalyst was characterized by FT-IR, XRD, TEM, XPS. The electrochemical performances indicate that the presence of ZrO2 modified the electro-structure of Pt on the catalyst surface and that ZrO2@CNx had superior oxygen reduction activity compared to a nitrogen-doped carbon coated carbon (C@CNx).enThis is the author-version of the article published online at: http://dx.doi.org/10.1016/j.ijhydene.2013.03.041ZrO2Nitrogen-doped carbonPt electrocatalystOxygen reduction reactionFuel cellArticle
