Ce0.8La0.2O1.9-attapulgite (Ce0.8La0.2O1.9-ATP) nanocomposite materials were synthesized by co-precipitation method. The microstructure and phase composition of the as-prepared samples were characterized by X-ray diffraction (XRD), Laser Raman spectroscopy (LRS), energy-dispersive spectrometer (EDS) and transmission electron microscopy (TEM). The redox properties of samples were investigated by phenol oxidation experiment. The results indicated that La3+ ions incorporated into CeO2 lattice and formed solid solution. The Ce0.8La0.2O1.9 particles with average size of about 10 nm were loaded onto the ATP and were widely dispersed. The catalytic activity was improved when La3+ was introduced. The catalytic property of Ce0.8La0.2O1.9-ATP nanocomposites for phenol was better than that of CeO2 and CeO2-ATP.
