摘要：

Highly ordered Ru-containing mesoporous carbons (Ru-OMC) were for the first time synthesized by a one-pot method. Comparing with our previously reported Ir-OMC, the Ru precursor must be added after the formaldehyde was consumed by polycondensation with resorcinol to obtain a small particle size. The resultant Ru-OMC samples with different Ru contents were characterized with X-ray diffraction (XRD), N(2) adsorption-desorption, and Transmission electron microscopy (TEM). The results evidenced the formation of highly ordered mesostructure, in which Ru particles were imbedded. The new carbon materials were further evaluated in the selective hydrogenation of cinnamaldehyde (CMA). By comparison with the traditional Ru/AC catalyst, our Ru-OMC samples exhibited much higher activity (2-14-fold) and up to 60% of selectivity to cinnamyl alcohol (CMO).
