Abstract: A method for forming a structured doped cerium oxide nanoparticle including the steps of forming a first aqueous cerium(lll) reaction mixture, with optional metal/s other than cerium, a base, and a stabilizer; introducing an oxidant to singly oxidize cerium (III), followed by thermal formation of a doped cerium oxide nanoparticle core; then providing a second reaction mixture of one or more metal ions other than cerium, and optionally cerium (III) ions and sufficient cerium (III) oxidant, followed by thermally converting the mixture into a shell around the doped cerium oxide nanoparticle core, wherein the ratio of metal ions in the core differs from the ratio of metal ions in the shell. The disclosed structured doped cerium oxide nanoparticle may exhibit cubic fluorite crystal structure and possess a diameter in the range 1 nm-20 nm. A dispersion of the developed nanoparticle may be used as a fuel additive.

Abstract: A process for making cerium dioxide nanoparticles containing at least one transition metal (M) utilizing a suspension of cerium hydroxide nanoparticles prepared by mechanical shearing of an aqueous mixture containing an oxidant in an amount effective to enable oxidation of cerous ion to eerie ion, thereby forming a product stream that contains transition metal-containing cerium dioxide nanoparticles, Cel-xMxO2, wherein "x" has a value from about 0.3 to about 0.8. The nanoparticles thus obtained have a cubic fluorite structure, a mean hydrodynamic diameter in the range of about 1 nm to about 10 nm, and a geometric diameter of less than about 4 run. The transition metal-containing crystalline cerium dioxide nanoparticles can be used to prepare a dispersion of the particles in a nonpolar medium.
