The method of preparation comprises: a step (a) of placing in solution at least one compound of at least one metal A in at least one organic solvent S, and of at least one reducing compound R of at least one metal B in at least one organic solvent S', a step (b) of placing the reducing compound R in contact with the metal A compound, a step (d) of neutralisation of the residual reducing functions of the reducing compound R with at least one oxidizing agent O, and where applicable the addition of a selectivity agent P either during step (a) or during step (c) placed between steps (b) and (d), The catalyst obtained can be used in selective or total hydrogenation. |
