Abstract
Organically functionalized metal nanoparticles are produced by mixing a metal precursor with an organic surface passivant and reacting the resulting mixture with a reducing agent to generate free metal while binding the passivant to the surface of the free metal to produce organically functionalized metal particles.
Claims14
A method for preparing organically functionalized nanocrystals of metals and metal alloys comprising the steps of:
- (a) providing a solution or dispersion of one or more metal salts;
- (b) providing a solution of a non-metallic organic surface passivant;
- (c) mixing said one or more metal salts with said non-metallic organic surface passivant;
- (d) reacting the resulting mixture with a reducing agent to reduce said one or more metal salts to free metal while concomitantly binding said non-metallic organic surface passivant to the resulting free metal surface;
- thereby providing organically functionalized metal and metal alloy nanocrystals having a particle diameter of 1-20 nanometers.
