采用浸渍法制备了一种负载在葡萄糖衍生碳球上的新型钌催化剂，然后通过X射线光电子能谱、X射线衍射、透射电子显微镜、扫描电子显微镜、傅里叶变换红外光谱和固态\(^{13}\)C魔角旋转核磁共振等技术对其进行了表征。以水作为环境友好型溶剂，在温和条件（反应温度 = 393 K，氢气压力 = 2.0 MPa）下，喹啉的转化率和对十氢喹啉的选择性分别可达到98.2%和95.2%。该催化剂可循环使用三次，活性和选择性均无下降。这种催化剂优异的催化性能可能归因于载体表面羟基与喹啉中氮原子之间的氢键以及有机载体与喹啉之间的π - π相互作用。
A new ruthenium catalyst supported on glucose‐derived carbon spheres was prepared by using the impregnation method and then characterized by X‐ray photoelectron spectroscopy, XRD, TEM, SEM, FTIR, and solid‐state 13C MAS NMR techniques. With water as the environmentally friendly solvent, the conversion of quinoline and the selectivity toward decahydroquinoline could reach 98.2 and 95.2 %, respectively, under mild conditions (reaction temperature=393 K and H2 pressure=2.0 MPa). The catalyst could be recycled thrice without decrease in activity and selectivity. The excellent catalytic performance of this catalyst may be attributed to the hydrogen bond between the hydroxyl group of the support surface and the nitrogen atom in quinoline as well as to the π–π interaction between the organic support and quinoline.
