Cerium oxide(CeO2) coated on copper modified attapulgite clay nanocomoposite(CeO2/Cu2+-ATP) was prepared by homogeneous deposition method.The microstructures of the as-prepared CeO2/Cu2+-ATP nanocomposites were characterized by X-ray diffraction(XRD),energy-dispersive spectrometer(EDS) and transmission electron microscopy(TEM).The results indicated that CeO2 particles with average size of about 5 nm were loaded onto the Cu2+-ATP and were widely dispersed.Comparing the catalytic activity of ATP/CeO2 and CeO2/Cu2+-ATP,the catalytic activity was improved when a small quantity of Cu2+ was introduced.The loading amount of CeO2 and reaction temperature had important effects on decolorization ratio of methyl orange(MO).When the loading amount and reaction temperature were 70% and 338 K,respectively,the decolorization ratio of MO reached over 99%,which showed excellent catalytic activity.
Cerium oxide (CeO2) coated on copper modified attapulgite clay nanocomoposite (CeO2 / Cu2 + -ATP) was prepared by homogeneous deposition method. The microstructures of the as-prepared CeO2 / Cu2 + -ATP nanocomposites were characterized by X-ray diffraction energy-dispersive spectrometer (EDS) and transmission electron microscopy (TEM). The results indicated that CeO2 particles with average size of about 5 nm were loaded onto the Cu2 + -ATP and were widely dispersed. Comparing the catalytic activity of ATP / CeO2 and CeO2 / Cu2 + -ATP, the catalytic activity was improved when a small quantity of Cu2 + was introduced. Loading amount of CeO2 and reaction temperature had important effects on decolorization ratio of methyl orange (MO) .When the loading amount and reaction temperature were 70% and 338 K, respectively, the decolorization ratio of MO reached over 99%, which showed excellent catalytic activity.
