Short communication : Synthesis of Ru Incorporated TiO2 and Application to Oxidation of Benzyl Alcohol with Molecular Oxygen

Young Yeong Kim

Abstract

We synthesized TiO2 (Rux/TiO2) incorporating TiO2 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 (O2). Especially, the catalytic activities increased as the contents of ruthenium in TiO2 increased without the formation of any byproducts.

초록

본 연구에서는 수열합성법을 이용하여, 한단계의 과정으로 TiO2와 Ru (Ruthenium)가 도입된 TiO2 (Rux/TiO2)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, TiO2에 도입된 Ru의 양이 증가할수록 촉매로서의 더 좋은 촉매활성을 보였다.
