Nanorod-like　Ce0.7Zr0.3O2　solid　solutions　were　synthesized　by　a　sodium　dodecyl　sulfate-assisted　precipitation　method.　The　samples　were　characterized　by　means　of　scanning　electron　microscopy,　transmission　electron　microscopy,　X-ray　diffraction,　Fourier　transform　infrared　spectroscopy,　and　specific　surface　area　measurement.　Typical　Ce0.7Zr0.3O2　nanorods　were　40　nm　in　average　diameter　and　450　nm　in　length,　with　specific　surface　area　and　oxygen　storage　capacity　of　194　m(2)/g　and　374　mu　mol/g,　respectively.　(C)　2010　Chinese　Society　of　Particuology　and　Institute　of　Process　Engineering,　Chinese　Academy　of　Sciences.　Published　by　Elsevier　B.V.　All　rights　reserved.
