Patent ID: 7632332

Claim:
A method of producing nanoparticles, comprising providing an iron-containing organometallic component and a titanium-containing organometallic component; contacting the iron-containing organometallic component and the titanium-containing organometallic component in the presence of a surfactant; heating the iron-containing organometallic component, the titanium-containing organometallic component and the surfactant to produce iron and titanium-containing nanoparticles; providing a metal-containing precursor; contacting the iron and titanium-containing nanoparticles with the metal-containing precursor; and heating the iron and titanium-containing nanoparticles and the metal-containing precursor to produce metal-capped iron and titanium-containing nanoparticles, wherein the metal-containing precursor comprises an organometallic component capable of forming metal-capped nanoparticles.
