ABSTRACT:
Metal nanoparticles containing two or more metals are formed by heating or refluxing a mixture of two or more metal salts, such as a metal acetates, and a passivating solvent, such as a glycol ether, at a temperature above the melting point of the metal salts for an effective amount of time.
