Key Points

This research aims to explore how curved interfaces in carbon supports influence the efficiency of oxygen reduction reactions in catalysts.
Utilized PtCo alloys anchored to MOF-derived carbon supports with curved morphologies.
Analyzed the local microenvironment effects on reaction kinetics and performance metrics.
Conducted performance tests comparing different carbon morphologies in the oxygen reduction reaction.
Curved carbon supports showed a significant increase in oxygen reduction reaction activity compared to flat surfaces.
The optimal PtCo alloy configuration achieved a 30% higher reaction rate (ORR) with a 95% CI, p<0.01.
Enhanced microenvironment at curved interfaces substantially improved catalyst durability over extended use.
