摘　　要：Supported Ru-based catalysts, prepared by a surfactant-stabilized colloidal method, exhibited a good selectivity to bis（4-aminocyclohexyl）methane via the hydrogenation of 4,4′-methylenedianiline. Transmission electron microscopy（TEM） and X-ray diffraction（XRD） characterization showed Ru nanoparticles were well-dispersed on activated carbon, leading to the high activity and selectivity to the product.Supported Ru-based catalysts, prepared by a surfactant-stabilized colloidal method, exhibited a good selectivity to bis（4-aminocyclohexyl）methane via the hydrogenation of 4,4′-methylenedianiline.
