Enhancing Electric Double Layer Capacitance of Two-Dimensional Titanium Carbide (MXene) with Facile Synthesis and Accentuated Properties

By 2030, energy storage stipulation will have tripled, necessitating the proliferation of various devices and systems. The discovery of graphene sparked an explosion of interest in two-dimensional (2D) material research. MXenes have a boundless range of potential applications, ranging from catalysis to electrochemical energy storage, by dint of their chemical diversity and electrical, mechanical, and optical properties. MXenes, or 2D transition metal carbides, carbonitrides, and nitrides, are formed by removing the A atom layer from the parent MAX phase with an etchant such as aqueous fluoride-containing acidic solutions. The physical and chemical attributes of Ti3C2, a member of the MXene family, make it a suitable electrode material for supercapacitors. Due to the large surface area of 649.171 m2 g–1 and its pore volume of 0.844 cm–3 g–1, the specific capacitance of the Ti3C2Tx increases at an unprecedented rate of charge storage up to 633 F g–1.
