Hydrothermal synthesis of transition metal oxide nanomaterials in HEPES buffer solution
چکیده انگلیسی

Various transition metal oxide (Co3O4, Mn3O4 and ZnO) nanostructures were readily synthesized in HEPES buffer solution (200 mmol/L, pH 7.40) via a simple hydrothermal method. The products were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and energy dispersive X-ray spectroscopy (EDX). It was found that the morphologies of the as-obtained transition metal oxide nanostructures were affected by the reaction temperature, HEPES/metal salt molar ratio and metal precursor. HEPES with two free nitrogen atoms (piperazine group) and terminal hydroxyl groups plays a critical role as a reactant and surfactant to prevent the transition metal oxide nanomaterials from aggregation.
