High surface area mesoporous LaFexCo1−xO3 oxides: synthesis and electrocatalytic property for oxygen reduction†
Abstract
The mesoporous LaFexCo1−xO3 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 Fe3+/Fe2+ redox couple and electrical conductivity.
