摘要：

Nanocrystalline ceria (CeO2) particles have been successfully prepared via sonochemical and microwave assisted heating routes from aqueous solutions containing (NH4)(2)Ce(NO3)(6), hexamethylenetetramine and poly ( ethylene glycol)-19000 ( PEG). The products were characterized by techniques such as powder X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, selected area electron diffraction, Brunauer-Emmett-Teller nitrogen adsorption and UV-Visible absorption spectroscopy. Analysis of the results showed that the products had uniform shape, narrow size distribution and displayed conspicuous quantum size effects.
