| Research Abstract |
Oxygen storage property of delafossite-type copper oxides and their structural stability under oxidative/reductive atmosphere at high temperature have been investigated. It is found that oxygen storage behavior of Cr containing delafossite was caused by reductive decomposition of the delafossite-phase to spine-type phase and metallic copper, and regeneration of the delafossite-phase under oxidative atmosphere. Oxygen storage property was controlled by adjustment of Cu-Cu distance in the delafossite lattice by means of cation substitution on octahedral site.
