Monodisperse and single-phase cerium oxide nanopowders were synthesized by mixed solvothermal route, Ce(NO3)3·6H2O as raw materials, poly (vinylpyrrolidone) (PVP) as stable agent. The cerium oxide nanopowders could be controlled from 50 to 60 nm by adjusting the ratio between ethanol absolute and water at 160 °C. With methanol instead of ethanol absolute, the reaction temperature could be lowered to 130 °C.
