A two-dimensional multi-shelled metal–organic framework and its derived bimetallic N-doped porous carbon for electrocatalytic oxygen reduction†
Abstract
We report a multi-shelled two-dimensional metal–organic framework (MOF), which is transferred to a Co/Ni-embedded bimetallic N-doped porous carbon. The bimetallic N-doped porous carbon exhibits high electrocatalytic activity and long-term stability toward the oxygen-reduction reaction (ORR) and Zn–air batteries.
