Stabilisation of nanostructured Ce0.2Zr0.8O2 solid solution by impregnation on Al2O3: a suitable way for production of thermally stable oxygen storage/release promoters for three-way catalysts
By impregnating gamma -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 calcination at 1100 degreesC for 24 h.
