ZIF-67-derived Co-NC@CoP-NC nanopolyhedra as an efficient bifunctional oxygen electrocatalyst†
Abstract
In this work, a highly efficient bifunctional electrocatalyst, Co/CoP embedded N-doped carbon (Co-NC@CoP-NC) nanopolyhedra, was derived by the thermal pyrolysis of ZIF-67 under an Ar atmosphere and a subsequent phosphidation process. The nanopolyhedra show excellent activity and stability for both the OER and ORR, which are attributed to the production of highly stable active CoP, and the intact protection of the Co by the N-doped carbon layers.
