Abstract

Doping of low levels of sodium onto the cation sites of ceria-zirconia mixed oxides allows reduction of the materials to take place at lower temperatures than undoped materials, a desirable property for practical applications in supports for redox catalysis. Synthesis is achieved in a single step under mild hydrothermal conditions directly from aqueous mixtures of metals salts at high pH.
