Aqueous Route to Size-Controlled and Doped Organophilic Ceria Nanocrystals

This paper presents an aqueous route to size-controlled and doped ceria nanoparticles using the Ce-oleate complex as a chemically modified precursor. In this synthesis, a hydrolytic condensation of Ce-oleate complex by aqueous ammonia solution at room temperature leads to 2.2 nm sized ceria nanocrystals. These products are dispersible in nonpolar solvents owing to the hydrophobic [...]
