Ordered mesoporous ruthenium containing carbon (Ru-OMC) catalyst with semi-embedded uniform Ru particle distribution was synthesized by using RuCl3/SBA-15 as a hard template. The sucrose both acts as the carbon precursor and Ru3+ stabilizer. The use of RuCl3/SBA-15 makes more exposed Ru surface available for reactants. The turnover frequency of the Ru-OMC catalyst for hydrogenation of benzene reaches ca. 35,000 h(-1) at 4 MPa, 110 degrees C, which is 12 times improvement compared with that of Ru/OMC catalyst prepared by impregnation. The Ru-OMC catalyst can be recycled more than 9 times without much loss of performance and aggregation of Ru nanoparticles. (C) 2012 Elsevier B.V. All rights reserved.
