Efficient Synthesis and Electrochemical Investigation of Co₃O₄:PdO/Pd Nanocomposite for High‐Performance Supercapacitor Electrode Material

Abstract

Presently, energy-related research topics, including storage and conversion, have garnered significant global attention. The urgent need to address climate change and environmental challenges, such as pollution resulting from the combustion of fossil fuels in vehicles leading to CO 2 emissions, has prompted researchers to intensify their efforts in the area of energy storage and efficiency. [1,2] Nanotechnology has made significant steps in recent years, particularly in the field of nanocomposites that offer the combined benefits of multiple materials. These nanocomposites have garnered substantial attention as potential solutions to global energy challenges due to their unique properties and versatile applications. [3] The sustainable future of energy demands clean and renewable energies as well as innovative devices for energy storage like batteries (lithium ion-LiBs) and supercapacitors (SCs). [4,5] In comparison with LiBs, SCs, microsupercapacitors (μSCs), and batteries have emerged as promising energy storage devices owing to their exceptionally high charge/discharge rates, impressive power and energy densities, environmentally friendly characteristics, and long-term cycling stability. These attributes have
