Abstract

Abstract: By taking inspiration from the catalytic properties of single‐site catalysts and the enhancement of performance through ionic liquids on metal catalysts, we exploited a scalable way to place single cobalt ions on a carbon‐nanotube surface bridged by polymerized ionic liquid. Single dispersed cobalt ions coordinated by ionic liquid are used as heterogeneous catalysts for the oxygen evolution reaction (OER). Performance data reveals high activity and stable operation without chemical instability. Abstract : Co‐operating : A scalable method was developed to get single cobalt ions on CNT surface with polymerized ionic liquid. The polymerized ionic liquid can adjust the electron structure of the atomically dispersed Co which is favorable for the oxygen evolution reaction. The tangled polymerized ionic liquid, as counter ion, make the Co ion stable on CNT surface.
