Metal alkoxide-derived Co@NC/NCNS as a highly efficient bifunctional oxygen electrocatalyst
Ying Wang, Hongjie Yuan, Fan Liu, Tianjun Hu
Abstract
A promising bifunctional catalyst integrating Co@NC units and porous structure carbon nanosheets (Co@NC/NCNS) is in situ prepared by the calcination and subsequent acid etching of a mixture containing metal alkoxide and melamine. Benefiting from the synergism among the active sites and porous structure, the optimal Co@NC/NCNS-800 exhibits superior activity for the ORR/OER.
