Key Points

This research aims to enhance the accessibility of active sites in ZIF-8-derived single-atom Fe-N-C catalysts using a dual-molten-salt strategy.
Utilized a dual-molten-salt approach with NaCl and KCl to modify ZIF-8-derived catalysts.
Examined the preservation of microporous structure and structural opening to create a micro–mesoporous network.
Conducted structural and catalytic performance analyses to assess accessibility and activity.
NaCl successfully preserved the microporous frameworks, maintaining structural integrity.
KCl significantly opened the structure, resulting in a hierarchical micro–mesoporous network.
The dual strategy led to a notable increase in active site accessibility, enhancing catalytic performance.

Implication

Demonstrates enhanced accessibility of active sites in single-atom catalysts, suggesting improved catalytic efficiency.

Abstract

We report a dual-molten-salt strategy to address the limited accessibility of ZIF-8-derived single-atom sites. NaCl preserves the microporous framework, while KCl promotes structural opening to generate a hierarchical micro–mesoporous network....
