Abstract Heating reflux aging technology was first applied to obtain a series of ceria zirconia mixed oxides composed of 0.6CeO2-0.4ZrO2. N2 physical adsorption, FT-Raman, and UV-Vis diffuse spectroscopy techniques were preformed to investigate the relationships between the structure and oxygen storage capacity of ceria zirconia mixed oxides prepared at different pH value of precipitation. The composition of ceria zirconia mixed oxides fluctuated with the pH value of precipitation, leading to the variation in phase ingredients, defects, crystallization and texture. Controlling the pH value of precipitation at 10.5-11.0 can avoid the introduction of Si, improve the texture, phase homogeneity and defects concentration, decrease the degree of crystallization, and increase the oxygen storage capacity.
