Abstract: The invention is directed to a process to prepare metal nanoparticles or metal oxide nanoparticles by applying a cathodic potential as an alternating current (ac) voltage to a solid starting metal object which solid metal object is in contact with a liquid electrolyte comprising a stabilising cation. The invention is also directed to the use of the nanoparticles as a catalyst.
