Continuous synthesis of organic–inorganic hybridized cubic nanoassemblies of octahedral cerium oxide nanocrystals and hexanedioic acid
Seiichi Takami, Satoshi Ohara, Tadafumi Adschiri, Yutaka Wakayama and Toyohiro Chikyow,
Dalton Trans., 2008, 5442
DOI: 10.1039/b801099d
We synthesized organic–inorganic hybridized cubic nanoassemblies of octahedral CeO2 nanocrystals, whose shape plausibly leads to octa-coordination of the primary nanocrystals, thus enabling controlled assembly to form a cubic structure.
