Abstract:
We develop a Bi-assisted pyrolysis method to fabricate rich-edge N-doped carbon anchored with Fe active sites using Fe-doped Bi-MOF as a precursor. During pyrolysis, Bi aggregation forms edge-rich nanobelts, while the subsequent Bi evaporation generates mesopores, increasing edge-hosted Fe site density. The resulting catalyst exhibits superior intrinsic activity and selectivity for CO2-to-CO, outperforming in-plane Fe single sites.
