    Supercapacitors are considered as newly developed auxiliary and clean supplies of power and energy for the next generation energy storage devices with significant impact in many fields. In the present investigation, Ag nanoparticles decorated over TiO2-ZrO2 films are used as the material for energy storage applications. The cyclic voltammograms of the proposed material show better specific capacitance values and robust cyclic stability. The results of the electrochemical measurements further show a strong double-layer electrical capacitance of ternary mixed oxides. The synergetic interaction among the components in the hierarchical nanostructured porous Ag@TiO 2-ZrO2 film guaranteed the good capacitive performance. The comparison between the TiO2-ZrO2 films and Ag decorated TiO 2-ZrO2 films bring out the strong interconnection between the constitution and composition of both systems and their properties. These results underline the exceptional electrical double layer capacitive behavior that is seen in porous ternary composite films with better surface area. Furthermore, such a simple and low-cost layer by layer assembly method with self-cleaning property can be used for the large-scale fabrication of diverse functional architectures for energy storage and conversions
