제목 | N-doped Carbon Coated Metals for Electrochemical Applications: Theoretical and Experimental Validation |
초록 | Recently, Zelenay et al. reported that the oxygen reduction reaction (ORR) activity of polyaniline-Fe carbon composite (PANI-Fe-C) is similar to that of Pt. Our previous work elucidated the behavior of 3d-transition metals such as Ni, Co, and Cu in the systems of N-doped graphene on metal supports (N-Gr/M) using first principles density functional theory (DFT). Simply speaking, the metals are able to change the electronic structure of N-Gr, and it plays a role of the positive effect for ORR reaction. Metal encapsulated at carbon shells (M@N-Cshells) based on theoretical study can be anticipated as a promising catalytic structure. In particular, nitrogen doped carbon is considered as the active sites of ORR catalysts. Hence, in this work, we synthesized FeCo@N-C nanoparticle and analyzed this material electrochemically and structurally in the view points of 1) Nitrogen doping effect, 2) carbon thickness effect and 3) alloying effect. |
