Abstract

The present study introduces a Co₃O₄ and Ti₃C₂Tₓ nanocomposite, synthesized via an ultrafast microwave-assisted method for electrochemical energy storage applications. Morphological and structural analyses indicated the formation of a nanoflower-like Co₃O₄-MXene nanocomposite, which is advantageous for the swift and efficient diffusion of electrolytes, thereby enhancing electrochemical performance. The growth of Co₃O₄ in a layered structure enhances ion diffusion. The Co₃O₄-MXene nanocomposite demonstrated a maximum specific capacitance of 868 F g⁻¹ at a current density of 1 A g⁻¹, along with excellent rate capability and cyclic stability. Furthermore, the assembled all solid-state asymmetric supercapacitor (ASC) exhibited an energy density of 10.41 Wh kg⁻¹ at a power density of 2500 W kg⁻¹, along with remarkable cycling stability, preserving 97.6 % of its initial capacitance after 5000 cycles. The obtained results demonstrate the significant improvement in electrochemical performance of Co₃O₄ due to addition of Ti₃C₂Tₓ.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
