Synthesis of Mo2C MXene with high electrochemical performance by alkali hydrothermal etching

Journal of Advanced Ceramics, 2023
Two-dimensional MXenes are generally prepared by the etching of acid solutions. The as-synthesized MXenes are terminated by acid group anions (F–, Cl–, etc.), which affect the electrochemical performance of MXenes.

Understanding the MXene Pseudocapacitance

The Journal of Physical Chemistry Letters, 2018
MXenes have attracted great attention as next-generation capacitive energy-storage materials, but the mechanisms underlying their pseudocapacitive behavior are not well understood. Here we provide a theoretical description of the surface redox process of Ti3C2T x (T = O, OH), a prototypical MXene, in 1 M H2SO4 electrolyte, based on joint density ...

MXene and MXene-based materials for lithium-sulfur batteries

Progress in Natural Science: Materials International, 2021
Abstract Lithium-sulfur (Li–S) batteries are regarded as potential alternatives to lithium-ion batteries due to their extremely high theoretical energy density. Nevertheless, Li–S batteries still suffer from low coulombic efficiency, low sulfur utilization, and poor cycling life, which hinder their further applications.
