We report the first successful synthesis of TiO 2 (B) nanoparticles by a one-step hydrothermal process. The process was performed under acidic conditions in a 0.59 M H 2 SO 4 solution at 160 °C for 24 h or at 200 °C for 6 h using a titanium metal complex with glycolic acid. The prepared nanoparticles were characterized by XRD, Raman spectroscopy, and TEM. TiO 2 (B) is a metastable phase and is one of the most intriguing forms of titanium oxide. All synthesis methods for TiO 2 (B) reported to date have required a multistep process involving solid-state synthesis of an alkali metal titanate, an ion-exchange reaction, and gentle dehydration.
