We synthesized cubic nanoassemblies of octahedral CeO(2) nanocrystals by simply heating an aqueous solution of cerium nitrate (Ce(NO(3))(3)) in the presence of hexanedioic acid (HOOC(CH(2))(4)COOH) in a lab-scale plug-flow reactor. It was concluded that the octahedral shape of the primary CeO(2) nanocrystals plausibly leads to octa-coordination of the primary nanocrystals, thus enabling controlled assembly to form a cubic structure.
我们通过在实验室规模的活塞流反应器中，在己二酸（HOOC(CH₂)₄COOH）存在的情况下简单加热硝酸铈（Ce(NO₃)₃）水溶液，合成了八面体CeO₂纳米晶体的立方纳米聚集体。得出的结论是，初级CeO₂纳米晶体的八面体形状可能导致初级纳米晶体的八配位，从而实现可控组装以形成立方结构。
