Abstract:
A method of making nanoparticle materials by metal salt reduction, said method comprising:mixing non-toxic metal salts in a solvent; adding a reducing agent to said solvent at a predetermined temperature; stabilizing nanoparticle dispersion; precipitating nanoparticles from said nanoparticle dispersion; and re-dispersing said nanoparticles into said solvent, wherein said non-toxic metal salts comprises a combination of an iron salt and a platinum salt, wherein said iron salt comprises any one of FeCl2, FeCl3, Fe(OOCR)2, Fe(RCOCHCOR)3, CoCl2, Co(OOCR)2, Co(RCOCHCOR)2, and wherein said platinum salt comprises any one of Pt(RCOCHCOR)2, and PtCl2, wherein R comprises an alkyl group.
