Abstract:
The mesoporous LaFe(x)Co(1-x)O3 oxides synthesized via a co-nanocasting method exhibit perovskite structure with ordered mesoporous structure and high specific surface area. These materials are electrocatalytically active and highly stable for oxygen reduction reaction (ORR) attributing to the Fe(3+)/Fe(2+) redox couple and electrical conductivity.
