Synthesis of Chromium Carbide MXene nanosheets and its electrochemical analysis for energy storage application

MXene, a well known 2D transition metal carbide or nitride based material has been proved to be promising material for energy storage application. This material has gained significant attention due to their mechanical, electrical properties. In our study, the potential of chromium carbide MXene as an electrode material for energy storage applications has been investigated. The Chromium Carbide MXene opens up new avenues for energy storage owing to its electrical conductivity, mechanical properties, and high surface area.<br/>Chromium MXene was synthesized by using FeCl₃, well known etchant to etch Al layer for Cr₂AlC and Ascorbic acid was used for the removal of by-products. Delamination of the layers was done by sonication the sample in DMSO. A comprehensive characterization of chromium carbide MXene, including structural, morphological and electrochemical has been performed to understand this material. Electrochemical performance is evaluated as an electrode material for Supercapacitor application in different electrolyte i.e. acidic, basic and neutral medium. Cyclic voltammetry and galvanostatic charge-discharge studies demonstrated energy storage capabilities of synthesized chromium carbide MXene with capacitance 188 F/g and energy density of 26.11Wh/Kg, excellent rate performance, and stability. This study sheds light on the potential of chromium carbide MXene as an electrode material for energy storage applications. The demonstrated electrochemical performance and the insights gained from this research pave the way for the design of MXene-based electrode materials, contributing to the development of energy storage devices.
