将低水平的钠掺杂到氧化铈-氧化锆混合氧化物的阳离子位点上允许材料的还原在比未掺杂的材料更低的温度下发生，这是用于氧化还原催化的载体中的实际应用的期望性质。合成是在温和的水热条件下直接从高pH值的金属盐的含水混合物在单一步骤中实现的。
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.
