Abstract

Ruthenium incorporated titanium oxides (Ru_xTiO₂) were prepared by a one-step hydrothermal method using Ti(SO₄)₂ and RuCl₃ as the precursor of Ti and Ru, respectively. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), Energy-dispersive X-ray spectroscopy (EDS) mapping, and BET were applied for the analyses of catalysts. Ruthenium atoms are well dispersed in the anatase phase of TiO₂ and the crystallite size of RuxTiO₂ (≈17 nm) is smaller than that of pure TiO₂ (≈45 nm). In particular, we found that our homemade pure TiO₂ exhibits a strong Lewis acid property. Therefore, the cooperation of ruthenium atoms playing a role in the hydride elimination and the Lewis acid site of TiO₂ can efficiently transfer primary alcohols into corresponding aldehydes in an oxidant-free condition.
