摘要：

Ce(OH)(3) particles with diameters of about 3-8 nm were deposited on the double-walled carbon nanotube (DWNT) bundles evenly by the chemical reaction of CeCl3 and KOH solution. The Ce(OH)(3)/DWNT films changed into CeO2/DWNT films by heating the samples to 450 degreesC for 20 min. The atomic ratio of Ce/C in the CeO2/DWNT film was about 1:35 calculating from the XPS spectra. The deposition mechanism of Ce(OH)(3) on DWNT bundles was also discussed. (C) 2004 Elsevier B.V.
