Abstract (en)
[origin: WO2007001418A2] Nanoparticles include a plurality of two or more dissimilar components selected from the group of noble metals, base transition metals, alkali earth metals, and rare earth metals and/or different groups of the periodic table of elements. The two or more dissimilar components are dispersed using a dispersing agent such that the nanoparticles have a substantially uniform distribution of the two or more dissimilar components. The dispersing agents can be poly functional small organic molecules, polymers, or oligomers, or salts of these. The molecules of the dispersing agent bind to the particle atoms to overcome same-component attractions, thereby allowing dissimilar components to form heterogeneous manoparticles. Dissimular components such as iron and platinum can be complexed using the dispersing agent to form sbstantially uniform heterogeneous nanoparticles. The nanoparticles can be used alone or applied to a support. At least a portion of the dispersing agent can be removed by reduction and/or oxidation.
