摘要：

Nanosized cuboid-like TiO2 with anatase-rutile structure was synthesized by using a microwave-assisted hydrothermal method. Silver nanoparticles, which were photoreduced on TiO2 P25 (STiO2), or TiO2 P25 was used as the precursor and HF was the source of F- ions, which played the role of capping agents. The synthesis was performed at pH 2 and 190 degrees C for 5 h. Fluorine species (HF) are important as stabilizing and shape-controlling agents which lead to the formation of TiO2 square-shaped plate nanoparticles. (C) 2014 Elsevier B.V. All rights reserved.
