Resolving Active-Site Heterogeneity in Fe–N–C Catalysts by Integrated Multimodal Spectroscopy and Simulation

Abstract Fe–N–C single-atom catalysts are among the most promising electrocatalysts for the oxygen reduction reaction (ORR), yet their atomic-scale structure remains difficult to resolve because high-temperature synthesis generates a diverse population of Fe sites. In this work,...

Electronic Communication Between Ferroelectric Surface Dipoles and Catalytic Active Sites Under Diverse Reaction Conditions

Abstract Dynamic modulation of the electronic environment of catalytic active sites offers a promising route to overcome the limitations of static catalyst design. One possible direction to achieve this goal is to induce catalyst dynamics via rapid inversion of the surface dipole...
