Abstract The reverse microemulsion system formed by cyclohexane/H2O/CTAB/n-butanol was used as the reaction medium. The aqueous phase was the sol formed by adjusting the pH of Ce(NO3)3 solution. The effect of concentration of Ce(NO3)3, temperature and pH of sol and the reverse microemulsion system on particle size of CeO2 was studied. The product was characterized by XRD and laser particle size analyzer. The results show that CeO2 particles with controlled particle size can be prepared within 1~100 nm. When the concentration of Ce(NO3)3 was 1.2 mol/L, the temperature of the sol and reverse microemulsion system was 25℃, and the pH of the reverse microemulsion system was 8, CeO2 particles having a D90 particle size of 25~45 nm can be obtained.
