Morphology-controlled synthesis of PbMoO₄ crystals by a simple sonochemical method

Abstract

PbMoO₄ nanoparticles and pagodalike microcrystals have been controllably prepared by a simple sonochemical method without any surfactants. The as-prepared powders were characterized by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The results showed that the pH played a crucial role on the controllable synthesis of PbMoO₄. Pagodalike microcrystals could be formed on acid condition, and nanocrystals were obtained in the case of pH 7 and pH 14. The synthesis mechanism was also discussed.
