摘要

Designing better cathode materials for solid oxide fuel cells can be aided by quantum-chemical calculations on oxygen reduction on Sr-doped LaMnO ₃ surfaces (La_0.5Sr_0.5MnO₃ = LSM0.5), which show that the reaction (see energy profile [eV]) proceeds via superoxo- (La-super and Mn-super) and peroxo-like (Mn-per) intermediates, dissociation and incorporation into the bulk (La-diss and Mn-diss), and diffusion to a more stable site (Product). YSZ = yttria-stabilized zirconia. (Figure Presented).
