Microemulsion-based synthesis of BaCO3 nanobelts and nanorods

The BaCO3 nanorods and nanobelts were successfully synthesized in CTAB/cyclohexane/H2O and NP10/cyclohexane/H2O microemulsion. The samples were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and infrared spectroscopy (IR). The possible mechanisms for the formation of BaCO3 samples in series of microemulsion systems were discussed. Various comparison experiments show that several experimental parameters, such as the concentration of surfactant and reactant, and solvent hydrothermal treatment play important roles in the morphological control of BaCO3 nanostructures.
