and characterized by transmission electron microscopy, small-angle X-ray scattering, and X-ray photoelectron spectroscopy. The catalyst obtained was tested in the hydrogenation of various substrates, such as aromatic and unsaturated compounds, phenols, levulinic acid and its esters for the first time. The catalyst activity was found to depend considerably on the substrate polarity and size. The size of
合成了基于 β-环糊精和环氧氯丙烷共聚物稳定的钌 (0) 纳米粒子的水溶性催化剂,并通过透射电子显微镜、小角 X 射线散射和 X 射线光电子能谱对其进行了表征。所获得的催化剂首次在芳香族和不饱和化合物、酚类、乙酰丙酸及其酯类等多种底物的加氢反应中进行了测试。发现催化剂活性在很大程度上取决于底物极性和尺寸。底物非极性部分的大小决定了它与载体的 β-环糊精部分形成包合物的倾向。对于芳香族化合物,后者充当保护基团。
