The electrochemical oxygen reduction reaction is the limiting half-reaction for low-temperature hydrogen fuel cells, and currently costly Pt-based electrocatalysts are used to generate adequate… (More)
We use microkinetic modeling to demonstrate that deviations from ideal Tafel kinetics, which assume a linear relationship between overpotential and log-current, are an inherent property of multi-step… (More)
Due to the immense phase space of potential alloy catalysts, any rigorous screening for optimal alloys requires simple and accurate predictive structure–reactivity relationships. Herein, we have… (More)
Broadly speaking, bottom-up catalyst design is based on detailed understanding of the molecular transformations that govern catalytic processes and controlling these transformations through targeted… (More)
Platinum-based electrocatalysts for fuel cells have been the subject of a vast collection of research over the past several decades. While the intrinsic area-specific activity of these materials has… (More)
Understanding the influence of potential on electrochemical surface reaction kinetics remains a challenge in identifying catalytic materials for numerous important reactions including water splitting… (More)
