Synthesis of Pr-doped ceria nanorods with a high specific surface area

Well monodispersed and large-scaled Pr-doped ceria nanorods were prepared via a high-temperature precipitation and low-temperature aging route without further sintering. X-ray diffraction, transmission electron microscopy and selected-area electron diffraction indicated that the as-prepared ceria nanorods had a cubic fluorite structure and the morphologies of the products were uniform, being ∼30 nm in diameter and ∼400 nm in length. The physisorption experiments showed a high specific surface area of Pr-doped ceria nanorods.
