1. Catalyst consisting of nanoparticles, said nanoparticles comprising:
a metal core containing at least one platinoid or an alloy of a platinoid,
a first organic coating formed from molecules attached to the surface of the metal core, and
a second organic coating formed from molecules different from the molecules of the first organic coating, and which are grafted onto molecules of the first organic coating,
wherein the molecules of the second organic coating are residues of a compound chosen from monocyclic and polycyclic anhydrides.
