CeO{sub 2} nanotubes have been synthesized facilely using carbon nanotubes (CNTs) as templates by a liquid phase deposition method. The properties of the CeO{sub 2} nanotubes were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectrum (XPS) as well as thermogravimetry and differential thermal analysis (TG-DTA). The obtained CeO{sub 2} nanotubes with a polycrystalline face-centered cubic phase have a uniform diameter ranging from 40 to 50 nm. The CeO{sub 2} nanotubes are composed of many tiny interconnected nanocrystallites of about 10 nm in size. The pretreatment of CNTs and calcination temperature were confirmed to be the crucial factors determining the formation of CeO{sub 2} nanotubes. A possible formation mechanism has been suggested to explain the formation of CeO{sub 2} nanotubes. - Graphical abstract: CeO{sub 2} nanotubes have been synthesized facilely using carbon nanotubes as templates by a liquid phase deposition method.
