摘要

An environmentally friendly and economically efficient method has been developed to synthesize monodisperse CeO2-ZrO2 solid solution nanocrystals. In this process, the formation of oleate-stabilized Ce0.5Zr0.5O2 nanocrystals was designed to proceed through hydrolytic sol-gel condensation of metal-oleate precursors in an aqueous solution and subsequent hydrothermal growth at 200 °C for 6 h. The results showed that the 3.0-nm-sized nanocrystals possess a metastable CeO 2-ZrO2 tetragonal phase with well-designed chemical composition and are nearly monodisperse. Owing to the uniform textural and elemental properties, the products exhibit relatively high thermal stability of the metastable phase and well-defined reduction properties.
