Abstract
The present invention provides a process for making nanoparticle based bulk materials. Also provided is a single component metal nanoparticle based bulk glass material comprising less than about 1% by weight of ligand capped nanocrystals; and wherein the metal is palladium.
Claims17
A process for making nanoparticle based bulk materials, said process comprising:
- (a) combining organic ligand associated nanocrystals in a non-polar solvent to form a first dispersion;
- (b) treating the first dispersion with a solution of an inorganic reagent in a polar solvent to yield inorganic ligand associated nanocrystals as a second dispersion;
- (c) isolating the inorganic ligand associated nanocrystals;
- (d) treating isolated inorganic ligand associated nanocrystals with a polar solvent to yield naked nanocrystals in the form of a powdery substance;
- (e) isolating and drying the powdery substance;
- and
- (f) subjecting the dry powdery substance to high pressure to yield a metal nanoparticle based bulk material.
4 more elements
A single component metal nanoparticle based bulk material comprising from about 8% to about 0.1% by weight of the ligand associated nanocrystals;
- and wherein the metal is palladium.
