Enhancing Electrochemical Performance through Li2Mn3ZnO8 Integration into Ti3C2Tx MXene Nanocomposites for Advanced Supercapacitors and Hydrogen Evolution Reactions

In this study, we combined Li2Mn3ZnO8 with MXene (Ti3C2Tx) to improve performance in supercapacitors and hydrogen evolution reactions. MXenes are known for their electrical conductivity and high surface area, making them promising for energy storage. The Ti3C2Tx/Li2Mn3ZnO8 composite electrode showed a specific capacitance of 182 F g-1 at 1 A g-1, outperforming individual Li2Mn3ZnO8 and MXene electrodes. Even after 3,000 cycles, the composite retained 71% of its initial capacitance. This research introduces innovative electrode materials for next‐generation supercapacitors and hydrogen evolution applications, contributing to sustainable energy solutions. The incorporation of Li2Mn3ZnO8 into Ti3C2Tx MXene nanocomposites significantly enhances the electrochemical performance in supercapacitors and hydrogen evolution reactions. This integration leads to an increase in pseudocapacitance, improved electrochemical stability, and reduced overpotentials, rendering it highly suitable for efficient energy conversion applications.
