A method to preparing suspensions of metal or metal alloy nanoparticles in an ionic liquid involves the physical vapor deposition of a metal or a mixture of metals onto an ionic liquid. The method can be modified by the introduction of a reagent during or after formation of the suspension to yield nanoparticles of a metal salt. The nanoparticles can be isolated from the suspension by the thermal decomposition of the ionic liquid under conditions where the decomposition products are gaseous.
