MXene titanium carbide synthesized by hexagonal titanium aluminum carbide with high specific capacitance and low impedance

Abstract

The electrochemical properties of MXene titanium carbide Ti3C2, which has received much attention in the application of electrode materials for supercapacitors, are affected by the different morphology of its precursor....

Fabrication of porous Ti3C2Tx MXene films by in situ foaming strategy for unparalleled high-rate energy storage

“…S3, † clearly display the uniform distribution of Ti, C, O, and F elements. The appearance of O and F elements should be attributed to the introduction of surface functional groups after etching, including -OH, vO, and -F. 19 Afterward, the etched multilayer powder was subjected to exfoliation by sonication. After sonication, MXene nanosheets with typical thin few-layer morphology were acquired, as proved in transmission electron microscopy (TEM) and SEM images in Fig.…”

Recent progress of MXene as an energy storage material

“…Wu et al introduced tetrabutylammonium fluoride on the basis of HCl and LiF, reducing the etching time to 2 hours. 36,37 The precursor used in the synthesis of MXene also affects the physical properties of the synthesized MXene. In Wu et al's work, 36 Ti 3 C 2 MXene was etched from the hexagonal Ti 3 AlC 2 precursor.…”
