Abstract:
This paper presents a reactive ion exchange synthesis method of nano-CeO2 with positive cerium preexchanged ion exchange resin as precursor and ( NH4) 2CO3 as precipitant. The resultant precipitate was dried at 100 ℃ for 12 h and then was calcined at 500 K in air. The effects of ion exchange temperature and reaction time on the diameter of CeO2 particle were discussed. The TEM images show that the samples prepared with one step reactive ion exchange method are composed of nano-club with the length about 300 nm.
Key words: ion exchange CeO2 nanoparticle
