Abstract
Sodium titanate nanosheets were prepared by a hydrothermal synthesis method under basic conditions. Ruthenium was introduced on the surface of sodium titanate nanosheets through an UV irradiation in the aqueous $RuCl_3$ solution. The crystal phase and morphology of synthesized samples were analyzed by X-ray diffraction, transmission electron microscopy and energy dispersive spectroscopy. In addition, the content of Ru was evaluated by inductively coupled plasma. It was proposed that a monomeric form of ruthenium was incorporated on the surface of sodium titanate. Ruthenium incorporated sodium titanates were applied to alcohol oxidation using molecular oxygen as an oxidant. The sample with 7% ruthenium showed a catalytic activity with a turnover frequency value of $2.1h^{-1}$ in oxidizing benzyl alcohol to benzaldehyde without any other byproducts at $105^{\circ}C$ and 1 atmosphere.
