Compositional Homogeneity

Performance tradeoffs related to surface area, compositional homogeneity at the oxide surface, and oxygen reduction reaction activity are discussed for perovskite oxide type catalysts synthesized using solid state reaction, hybrid sol–gel, and aerogel synthesis techniques.
