Much effort has been devoted to the synthesis of novel nanostructured materials because of their unique properties and potential applications. Bismuth subcarbonate ((BiO){sub 2}CO{sub 3}) is one of commonly used antibacterial agents against Helicobacter pylori (H. pylori). Different (BiO){sub 2}CO{sub 3} nanostructures such as cube-like nanoparticles, nanobars and nanoplates, were fabricated from bismuth nitrate via a simple solvothermal method. The nanostructures were characterized by powder X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). It was found that the solvents and precursors have an influence on the morphologies of (BiO){sub 2}CO{sub 3} nanostructures. The possible formation mechanism of different (BiO){sub 2}CO{sub 3} nanostructures fabricated under different conditions was also discussed. - Graphical abstract: Different bismuth subcarbonate ((BiO){sub 2}CO{sub 3}) nanostructures were successfully synthesized by a simple solvothermal method.
