摘要

我们开发了一种双辅助热解方法，以掺铁的Bi-MOF为前驱体制备具有铁活性位点的富边n掺杂碳。在热解过程中，Bi聚集形成富边纳米带，而随后的Bi蒸发产生介孔，增加了边载Fe位密度。所得催化剂表现出优异的内在活性和co -to- co的选择性，优于平面内Fe单位点。

Edge-hosted Fe single-atomic sites fabricated by a Bi-assisted pyrolysis strategy for electroreduction of CO2†

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.
