Ironplatinum nanoparticle may be synthesized by either usage of incident laser technology  or by coreduction of chloroplatinic acid, an inorganic compound also known as hexachloroplatinic acid, and iron chloride in a water-in-oil micro-emulsion.
One method of synthesis uses incident laser technology to irradiate solutions containing iron and platinum to combine the two alloys. An alternative method of synthesis involves the coreduction of chloroplatinic acid (H2PtCl6) and iron (II) chloride in water-in-oil microemulsions. Chloroplatinic acid (also known as hexachloroplatinic acid) is an inorganic compound with the formula [H3O]2[PtCl6](H2O)x (0  x  6).
