Reversible changes in the redox behaviour of a Ce0.68Zr0.32O2 mixed oxide: effect of alternating the re-oxidation temperature after reduction at 1223 K
Abstract
The redox behaviour of a Ce0.68Zr0.32O2 mixed oxide is reversibly modified by alternating high temperature (1223 K) reduction with either mild (823 K) or high temperature (1223 K) re-oxidation treatments.
