Abstract：

Cerium　oxide　nanoparticles　with　single　crystal　were　prepared　by　precipitation　method　using　Ce(NO3)3·6H2O　as　cerium　resource　and　NH3·H20　as　precipitant　through　controlling　aging　time.　The　phase　structure,　morphology　and　nanosize　were　characterized　by　means　of　XRD,　TEM,　ED,　BET　and　TG-DTA.　XRD　result　shows　that　the　nanoparticles　CeO2　prepared　by　precipitation　are　fluorite　structure　with　high　crystallization　integrity.　The　size　of　particles　can　be　controlled　by　adjusting　the　temperature　of　thermal　treatment　and　aging　time.　The　results　of　TEM　and　ED　show　that　the　particles　are　spherical,　dispersed　well　and　single　crystal.　The　products　of　CeO2·1/2H2O　can　be　deduced　according　to　the　result　of　TG-DTA.
