The present invention relates to novel metal compounds, a process for the preparation of these metal compounds and their use as catalysts. The new metal compounds according to the invention have, when they are used as catalysts, in particular as hydrogenation catalysts, an efficiency of the same order as that obtained with Raney nickel or cobalt. These metal compounds are more precisely compounds comprising one or more divalent metals at least partly in the reduced state, textures with a phase comprising one or more doping metals chosen from chromium, molybdenum, iron, manganese, titanium. , vanadium, gallium, indium, bismuth, yttrium, cerium, lanthanum and other trivalent lanthanides, in the form of oxides. |
