摘要
Abstract
Poly(ethylene glycol) (PEG)-stabilized amorphous RuB nanoparticles were prepared and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). Results showed that Ru was reduced to zero valence and the average particle diameter of the RuB crystallites was about 2.4 nm. This catalytic system shows excellent activity and selectivity for the hydrogenation of pyridine and its derivates. At a reaction temperature of 100℃, a hydrogen pressure of 3.0 MPa, a reaction time of 60 min and using a molar ratio of 1/670 Ru to pyridine, the conversion of pyridine was found to be >99.0% and the selectivity for piperidine was 100%. The activity of the catalyst for substrates with different substituents was as follows: 2-methylpyridine>2,6-dimethylpyridine>pyridine.关键词
