Abstract
This work is focused on the ceria zirconia mixed oxide prepared through a surfactant‐introduced synthesis method. High surface area nanoparticle mesoporous ceria/zirconia‐mixed oxide was successfully synthesized and characterized using various techniques. High surface area mesoporous fluorite‐structured CeO~2~ZrO~2~ was obtained from the elimination of surfactants upon calcination. A surface area in excess of 205.6 m^2^/g was obtained after calcination at 500 °C, and dropped to 75.96 m^2^/g by heating at 900 °C. Temperature‐programming reduction (TPR) results showed that the lowest reduction temperature was obtained from the sample containing 40% zirconia content. Copyright © 2008 John Wiley & Sons, Ltd.
