摘要：
The aluminum oxide supported ruthenium catalysts were prepared by impregnation and polyol method (i.e., Ru/Al2O3-IMP and Ru/Al2O3-CRP), and their performance in the hydrogenation of 2-ethylanthraquinone (2-eAQ) was investigated. It was found that the catalysts prepared by different methods were all active and the Ru/Al2O3-CRP catalyst exhibited relatively high catalytic activity and stability. The catalysts were characterized by inductively coupled plasma atomic emission spectrometry (ICP-AES), X-ray diffraction (XRD), transmission electron microscopy (TEM) and photoelectron spectroscopy (XPS). The XRD and TEM results suggested that Ru particles were highly dispersed on the surface of the support. In addition, the Ru/Al2O3-CRP catalyst exhibited a low electron cloud density of Ru according to the XPS results, which made the Ru active sites more attractive to the lone pair electrons on the oxygen of 2-eAQ, and hence was conducive to activation of 2-eAQ. © 2021, Chemical Industry Press Co., Ltd.
