在实验室推流反应器中，通过加热硝酸铈(Ce(NO3)(3))在己二酸(HOOC(CH2)(4)COOH)存在下的水溶液，我们合成了立方结构的八面体CeO2纳米晶。结果表明，CeO2纳米晶的八面体形状可能导致了纳米晶的八配位，从而使可控组装形成立方结构。
We synthesized cubic nanoassemblies of octahedral CeO2 nanocrystals by simply heating an aqucous solution of cerium nitrate (Ce(NO3)(3)) in the presence of hexanedioic acid (HOOC(CH2)(4)COOH) in a lab-scale plug-flow reactor. It was concluded that the octahedral shape of the primary CeO2 nanocrystals plausibly leads to octa-coordination of the primary nanocrystals, thus enabling controlled assembly to form a cubic structure.
