Synthesis of CeO2/TiO2 nanoparticles by laser ablation of Ti target in cerium (III) nitrate hexahydrate (Ce(NO3)3·6H2O) aqueous solution

A new synthesis process, laser ablation in an aqueous solution of target material, was applied to synthesize nanostructured CeO2/TiO2 catalyst particles. Reactivity within the laser plume (plasma) can be used to synthesize CeO2 from an aqueous solution, 2M cerium (III) nitrate hexahydrate (Ce(NO3)3·6H2O) aqueous solution, and to fabricate TiO2 from Ti target. CeO2/TiO2 nanoparticles were successfully synthesized by the laser ablation of Ti target in 2M cerium (III) nitrate hexahydrate (Ce(NO3)3·6H2O) aqueous solution. Laser ablation of Ti in a liquid environment and chemical reactions of the solution within a plasma plume are discussed.
