A layered ultra-stable metal–organic framework for high loading of zinc single-atom oxygen electrocatalyst

Abstract

The activity and stability of atomically dispersed transition-metal (M–N–C)-based electrocatalysts are often limited by low metal loading and graphitization of the carbon framework, respectively. We report the synthesis of a Zn–N–C catalyst with high loading of Zn single-atoms (2.52 wt%) from a thermally stable, 2D metal–organic framework.
