摘　　要：A novel method of direct synthesis of CeO2 nanoparticles onto multi-walled carbon nanotubes （MWNTs） was developed with advantages of simplicity, ease of scale-up, and low costs. The size of CeO2 particles deposited on the MWNTs was less than 6 nm. SEM and TEM were em-ployed to analysis the CeO2 coated MWNTs, and the properties of FTIR spectrum and UV-vis ab-sorption spectrum were investigated. The functional groups on the MWNTs obtained by nitric acid treatment play an important role on the deposition of the CeO2 particles. The carbon nanotubes possess broadened UV absorption function after being coated with CeO2 nanopartilces.A novel method of direct synthesis of CeO2 nanoparticles onto multi-walled carbon nanotubes （MWNTs） was developed with advantages of simplicity, ease of scale-up, and low costs.
