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

Abstract

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 Ti3C2T x increases at an unprecedented rate of charge storage up to 633 F g–1.

“…Consequently, the larger specific surface area might be attained on the Ti 3 C 2 MXene-based photocatalyst for delivering larger surface-active sites to improve the photocatalytic performance. Also, a large surface area and pore volume of TiC may result in an increase in the specific capacitance to an unprecedented rate of charge storage . Ti 3 C 2 T x MXene shows broad spacing in the layers in which the ions can travel easily, while the presence – OH and – O groups present on the MXene surface offer outstanding conductivity.…”

“…The band around 3426.7 cm −1 corresponds to the stretching vibration mode of the hydroxyl group (–OH), thus confirming the presence of water molecules. The peaks at 3659.8, 3595.9, and 1632.2 cm −1 in Mxene are related to the -OH bending which had been allocated to adsorb H 2 O, confirming to MXene’s hydrophilic character [ 35 ]. In addition, the peaks at 568.2 and 455.9 cm −1 are indicative of Fe–O stretching and the bending vibrations of octahedral FeO 6 , indicating the existence of the BiFeO 3 phase [ 36 ].…”

“…Additionally, a peak at 1322 cm À1 may be attributed to the O H bond's bending vibration. 40,41 Figure 3(B) represents the typical FTIR spectra of p-and O-MWCNTs with different functional groups. In Figure 3(B), the FTIR spectrum of p-MWCNTs displays the characteristic peaks in the 3500-3800 cm À1 region, confirming the occurrence of OH bonds that may be moisture absorbed from the air.…”
