Abstract

To elucidate the effect of CeO₂ shape and doping on activity, Cu_0.02Ce_0.98O_2−δ and Cu_0.02Ce_0.86RE_0.12O_2−δ (RE = La and Pr) were synthesized by a molecular precursor approach. The materials showed distinct activities depending on the shape and composition of CeO₂, which was well correlated with their different oxygen storage capacities.
