With this aim, we report here the preparation of highly dispersed bimetallic Ni/Co nanoparticles (NPs), by a one-pot deposition-precipitation of Ni and Co phases onto mesoporous SBA-15 silica. By adjusting the chemical composition in the starting mixture, three supported catalysts with different Ni to Co weight ratios were obtained, which were further subjected to treatments under reducing conditions at high temperatures. Characterization of the resulting solids evidenced a homogenous distribution of Ni and Co elements forming the NPs, the best results being obtained for Ni/Co-2:2 samples, for which 50 wt.% Ni – 50 wt.% Co NPs are found located on the surface of the residual phyllosilicate. Ni/Co-2:2, presenting the best performances for the hydrogenation of 2-methyl-quinoline, was further evaluated in the catalytic hydrogenation of selected imines, oximes and N-heretoarenes. Due to the high dispersion of bimetallic Ni-Co NPs, excellent properties (activity and selectivity) in the conversion of the selected substrate are reported.Lire moins >
