The mixed metal oxides has been used as catalyst in different trasformations such as Oxidation, Reduction, Condansation etc reactions because of they consist of various active centers, different morphology and particle size. These mixed metal oxides are also have electrochemical properties are Lithium ion batteriy, Pseudocapacitors, Dye Sensitized Solar Cells, Supercapacitor. All these properties enhance the multifunctional character of mixed metal oxides.
