Abstract

Multi-component particles comprising inorganic nanoparticles distributed in an organic matrix and processes for making and using same. A flowing aerosol is generated that includes droplets of a precursor medium dispersed in a gas phase. The precursor medium contains a liquid vehicle and at least one precursor. At least a portion of the liquid vehicle is removed from the droplets of precursor medium under conditions effective to convert the precursor to the nanoparticles or the matrix and form the multi-component particles.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of Provisional Patent Application Ser. No. 60 / 599,847, filed on Aug. 7, 2004, the entirety of which is incorporated herein by reference.FIELD OF THE INVENTION

[0002] The present invention relates to inorganic nanoparticles. More particularly, the invention relates to multi-component particles comprising inorganic nanoparticles distributed in an organic matrix, and to processes for making and using such multi-component particles. BACKGROUND OF THE INVENTION

[0003] Nanoparticles, and processes for making nanoparticles, have been the subject of recent interest and research because of the advantages provided by nanoparticles over larger sized particulate materials. One advantage of nanoparticles is they have a greater surface area and surface energy, which is useful in a variety of applications, including catalysis, electrocatalysis, absorbance, chemical separations and bio-separation applications. Nanopar...
