Dynamic observation of manganese adatom mobility at perovskite oxide catalyst interfaces with water
Abstract
Atomic processes on the surface of a catalyst control reaction mechanisms. Here, in-situ imaging of manganese adatom dynamics on La0.6Sr0.4MnO3 and Pr0.67Ca0.33MnO3 surfaces used in the oxygen evolution reaction reveals the importance of partial surface solvation of active metal sites on reaction mechanism.
