Controlled synthesis of bismuth oxo nanoscale crystals (BiOCl, Bi{sub 12}O{sub 17}Cl{sub 2}, {alpha}-Bi{sub 2}O{sub 3}, and (BiO){sub 2}CO{sub 3}) by solution-phase methods

We present the controlled solution-phase synthesis of several sheet- or rod-like bismuth oxides, BiOCl, Bi{sub 12}O{sub 17}Cl{sub 2}, {alpha}-Bi{sub 2}O{sub 3} and (BiO){sub 2}CO{sub 3}, by adjusting growth parameters such as reaction temperature, mole ratios of reactants, and the base used. BiOCl, Bi{sub 12}O{sub 17}Cl{sub 2}, and {alpha}-Bi{sub 2}O{sub 3} could be prepared from BiCl{sub 3} and NaOH, whereas (BiO){sub 2}CO{sub 3} was prepared from BiCl{sub 3} and urea. BiOCl and Bi{sub 12}O{sub 17}Cl{sub 2} could also be prepared from BiCl{sub 3} and ammonia. The {alpha}-Bi{sub 2}O{sub 3} sample exhibited strong emission at room temperature. - Graphical abstract: We prepared bismuth oxo nanomaterials by adjusting growth parameters.
