Recent advances in mesoporous nanostructured materials and nanohybrids for supercapacitor applications: a review

Abstract

Mesoporous nanomaterials and nanohybrids have grabbed the attention of researchers for supercapacitor applications with their unique structural attributes and enhanced electrochemical properties. Recent developments have focused on optimizing the synthesis process and functionalization to achieve higher specific surface areas, tailored pore structures, and improved conductivity. These advancements are important for regular improvements in power density, cycling stability, and energy density of supercapacitors. Regardless of this, the challenges remain, particularly in the scalability of synthesis processes; the integration of nanohybrids with diverse materials enhances the long-term cycling stability under practical operating conditions. Prospects are promising, with ongoing research directed towards novel material combinations, advanced fabrication techniques, and the development of environmentally sustainable processes. Emerging trends suggest that the integration of technology could further accelerate the design and optimization of mesoporous nanomaterials and nanohybrids for developing future supercapacitors. This review article focuses on the theoretical and fundamental aspects of charge storage mechanisms for supercapacitor applications with respect to mesoporous nanomaterials and nanohybrids.
