3D Porous Nitrogen-rich Octahedral Carbon as advanced Oxygen Reduction Reaction catalyst

Abstract

A Metal-organic-frameworks (MOFs) derived 3D porous nitrogen-rich octahedral carbon (PNOC) catalyst is successfully fabricated via carbonization of MIL-101(Fe) precursor process. As-obtained PNOC combines the advantages of high surface area, well permeable pore and rich nitrogen content in one catalyst, which shows excellent catalytic activity and stability for oxygen reduction reaction (ORR). This work would offer some new insights to advanced ORR electrocatalyst material designed in fuel cells.
