Contribution of Mg-templated porosity to activity and durability in Fe–N–C O 2 reduction catalysts
Key Points
This research investigates how Mg-templated porosity affects the performance of Fe–N–C catalysts in CO2 reduction.
Analyzed the formation of Mg-templated pores ranging from 1 to 4 nm.
Evaluated the activity of Fe–N–C catalysts under acidic conditions.
Assessed the degradation of catalysts during O2 reduction reactions.
A strong correlation was found between pore formation and catalytic activity.
Increased pore size was linked to reduced catalyst degradation.
Catalysts with optimized porosity showed enhanced performance in CO2 reduction.
Abstract
The formation of Mg-templated pores within 1–4 nm strongly correlates with activity and degradation of Fe–N–C catalysts for the acidic O 2 reduction reaction.
