文摘

•: Kinetics of oxygen reduction on nanostructured La₂NiO_4+δ are determined.
•: Surface steps, such as electron transfer/oxygen vacancy healing, play a key role.
•: Nanostructure of La₂NiO_4+δ affects the energetics associated with ORR.
•: SOFCs containing La₂NiO_4+δ nanorods exhibit the best performance.
