Abstract
- To avoid the agglomeration of iron NPs and improve the dispersion of Fe SAs, we employed a mixed-ligand strategy to regulate the iron content in PCN-224(Zn<subscript>x</subscript>Fe<subscript>y</subscript>) and PCN-222(Zn<subscript>x</subscript>Fe<subscript>y</subscript>). Thanks to the sublimation of Zn and the Kirkendall effect, uniform dispersions of Fe SAs with 1.04–1.06 wt% were obtained in the pyrolysis products Zn<subscript>0.5</subscript>Fe<subscript>0.5</subscript>–N–C-224 and Zn<subscript>0.5</subscript>Fe<subscript>0.5</subscript>–N–C-222 with excellent CO<subscript>2</subscript> → CO activity, super-stability, and recyclability.
