Abstract: The immobilization of metal nanoparticles in the framework of porous carbon for heterogeneous catalysis may avoid particle aggregation, movement, and leaching, thus leading to a high catalyst efficiency. In this Full Paper, an approach to prepare Ru nanoparticles incorporated into the pore walls of porous carbon to form a sandwiched Ru/C nanostructure for heterogeneous hydrogenation is demonstrated. Physical adsorption of nitrogen, X-ray diffraction, thermogravimetric analysis, field-emission transmission electron microscopy, field-emission scanning electron microscopy, and energy dispersive X-ray spectroscopy techniques are employed to study the structure and morphology of the catalysts. Catalytic results show that the Ru nanoparticles sandwiched in the pore walls of porous carbon display a remarkably high activity and stability in the hydrogenation of benzene. An enhanced hydrogen spillover effect is believed to play a significant role in the hydrogenation reaction because of the intimate interfacial contact between Ru nanoparticles and the carbon support. The catalyst system described in this work may offer a new concept for optimizing catalyst nanostructures. © 2007 WILEY-VCH Verlag GmbH & Co. KGaA.
