Abstract: With the increasing requirements of performance of composite oxides,developing high-performance ternary composite oxides has attracted attentions of researchers in many fields.The synthesis and application of these new materials is of great significance.This paper introduces three commonly used preparation methods of the ternary composite oxides:solid phase method,sol-gel method,coprecipitation method as well as the effect of reaction temperature,mole ratio and pH on their performance.The research progress of ternary composite oxides in the field of catalysis,environmental protection and new energy in recent years are reviewed,and the development prospect are also discussed.Analysis shows that each element in the ternary composite oxide system has different contributions to the materials giving rise to maximize composite materials properties,and higher activity and stability than those of binary complex oxides.Finally,we figure out the research focus of ternary composite oxides is to explore synthetic methods for special performance,which lays a good foundation for the future industrial application.

Key words: composites, preparation, catalysis, influence factor
