Abstract

The invention relates to metal-nanoparticles and to methods for the production thereof in which a metallic salt solution is reduced by means of a reducing agent in the presence of the derivatised polyethylenimines or polyvinylamines. Metal salt solutions of two or more different metals can be reduced at the same time or successively. The metallic nanoparticles are obtained from two or more different metals. Metals are preferably silver, palladium and platinum. Suitable reducing agents are, for example, formic acid, formaldehyde, diethanolamine, 5-pentenic acids and sodium borohydride. Silver can be used in the form of silver oxide and/or silver nitrate, palladium can be used in the form of alkali tetrachloropalladate or palladium(ll)nitrate and platinum can be used in the form of alkali tetrachloroplatinate or tetraamine platinum(ll)nitrate.
