EnglishBy impregnating γ-Al2O3 with cerium/zirconium citrate solutions and subsequent calcination nanostructured CemZr1-mO2 mixed oxides supported on Al2O3 are obtained, which feature remarkably high oxygen storage even after a calcination at 1373 K for 24 h. Mutual thermal stabilisation between alumina and solid solutions has been observed, which prevents formation of α-alumina and sintering effects after a severe ageing.
