An efficient and stable Ru-Ni/C nano-bimetallic catalyst with a comparatively low Ru loading for benzene hydrogenation under mild reaction conditions

A prepared 0.024%Ru-1.00%Ni/C nano-bimetallic catalyst reported in this work is a highly efficient and stable catalyst for the hydrogenation of benzene to cyclohexane, with an unprecedented TOF up to 7905 h-1 under mild reaction conditions (20°C, 40 psi H2) without adding any solvent. The method for the preparation of catalyst is very simple and low-cost. Therefore, this cyclohexane synthetic approach is potentially more environmentally friendly and economical than existing technology. ? 2013 The Royal Society of Chemistry
