Controlled Synthesis of Nanorods/Nanorings of a Novel Co—Cu Complex in
Microemulsion at Room Temperature. — [Co(NH3)6]3[Cu4(OH)(CO3)8]·2H2O nanorods with diameters of 100—200 nm and nanorings with a ring-diameter of 80 nm are
synthesized from Cu(NO3)2, K2CO3, KHCO3, and Co(NH3)6Cl3 in a CTAB—water—cyclohexane—n-pentanol (CTAB: cetyltrimethyl ammonium bromide) microemulsion at room temperature. In this process, the addition of Co(NH3 )36 + to aqueous solutions of Cu2+ in excessive carbonate promotes the assembly of a new highly charged
carbonato-copper(II) anion, [Cu4(OH)(CO3)8]9-. — (SUN, G.; CAO, M.; WANG, Y.;
