摘要：

Uniform ammonium oxotrifluorotitanate (NH4TiOF3) mesocrystals were synethsized from an aqueous solution containing (NH4)(2)TiF6 and H3BO3 in presence of nonionic surfactant. Effects of various reaction conditions on the morphology of the NH4TiOF3 mesocrystals were examined by electron microscopy techniques. Results indicate that static solution, high surfactant concentration and low reaction temperature enhance the formation of uniform NH4TiOF3 mesocrystals with regular shapes. By sintering in atmosphere, the NH4TiOF3 mesocrystals were convereted to anatase TiO2, which retain the original shapes of the NH4TiOF3 precursor due to similarities on their atom structures.
