- •
Kinetics of oxygen reduction on nanostructured La2NiO4+δ are determined.
- •
Surface steps, such as electron transfer/oxygen vacancy healing, play a key role.
- •
Nanostructure of La2NiO4+δ affects the energetics associated with ORR.
- •
SOFCs containing La2NiO4+δ nanorods exhibit the best performance.
