摘要
Polydopamine-modified MCM-41 was prepared by sodium periodate-induced polymerization. Ru-La supported on MCM-41 and polydopamine-modified MCM-41 catalysts were prepared by double solvent impregnation method and tested for benzene hydrogenation to cyclohexene. Polydopamine-modified MCM-41 supported Ru-La catalyst exhibits much higher hydrophilicity and more moderate catalytic activity than unmodified MCM-41 supported Ru-La catalyst. The higher hydrophilicity, more moderate catalytic activity, and long-range order of mesoporous structure are beneficial for improving cyclohexene selectivity on account of the promotion of the desorption and the inhibition of the adsorption of cyclohexene. 47.0% of cyclohexene yield was obtained over Ru-La supported on polydopamine-modified MCM-41 in benzene hydrogenation.
