Abstract

We synthesized $TiO_2$ ($Ru_x/TiO_2$) incorporating $TiO_2$ and Ru via an one-step hydrothermal method. The physical properties were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The prepared samples were applied as a catalyst for the oxidation of benzyl alcohol to benzaldehyde using molecular oxygen ($O_2$). Especially, the catalytic activities increased as the contents of ruthenium in $TiO_2$ increased without the formation of any byproducts.

본 연구에서는 수열합성법을 이용하여, 한단계의 과정으로 $TiO_2$와 Ru (Ruthenium)가 도입된 $TiO_2$ ($Ru_x/TiO_2$)를 합성하였다. 합성된 샘플의 결정성과 조성 및 형태를 X-ray diffraction (XRD)과 energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM)를 통하여 확인하였으며, Benzyl alcohol의 Benzaldehyde로의 산화반응에 촉매로서 적용하였다. 높은 선택성을 가지는 산화반응이 진행되었으며, $TiO_2$에 도입된 Ru의 양이 증가할수록 촉매로서의 더 좋은 촉매활성을 보였다.
