Synthesis of Nanometer Cobalt Oxide (Co3O4) Powders by Solid-State Reaction under Microwave Irradiation
Nanometer cobalt oxide powders were obtained by decomposition of precursors CoC2O4×2H2O at 350°C for 3h. The precursors were synthesized by solid-state reaction with H2C2O4×2H2O and CoCO3 under microwave irradiation. The products were characterized by XRD and TEM. The results showed that the nanometer Co3O4 is cubic and the mean particle is 19 nm with narrow distribution and weak agglomeration.
