Hydrothermal Synthesis and UV Absorption Property of Firewood-Like CeO₂ Nanostructures

Abstract:

In this paper, we reported that firewood-like CeO₂ nanostructures were synthesized via hydrothermal method in the present of cetyltrimethylammonium bromide (CTAB) for the first time. X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) were used to characterize the as-obtained sample. The UV absorption property of the product was investigated by UV-vis spectrophotometry. XRD result shows that the product was a cubic fluorite-type CeO₂ phase with good crystallinity. FE-SEM and TEM analysis indicate that the firewood-like CeO₂ nanostructures were composed of CeO₂ nanoparticles with the average size of about 6-10 nm. The CeO₂ shows excellent UV absorption for that the transmittance (T %) of the sample in the UV region almost equal to zero.
