Abstract As an emerging star of 2D nanomaterials, transition metal carbides and nitrides, named MXenes, present a large potential in various research areas owing to their intrinsic multilayer structure intriguing physico‐chemical properties. However, the fabrication application functional MXene‐based devices still remain challenging as they are prone oxidative degradation under ambient environment. Within this review, preparation methods MXenes focusing on recent investigations thermal structure–stability relationships inert, oxidizing, aqueous environments systematically introduced. Moreover, key factors that affect oxidation such as, atmosphere, temperature, composition, microstructure, environment, reviewed. Based different scenarios, strategies for avoiding or delaying proposed encourage utilization complicated environments, especially at high temperature. Furthermore, chemistry MXene‐derived oxides is analyzed, which can offer perspectives further design novel composites with unique structures being preserved.

Recent progress in MXene layers materials for supercapacitors: High‐performance electrodes

SmartMat, Journal Year: 2022, Volume and Issue: 4(1)

Published: June 15, 2022

Abstract In 2011, Gogotsi et al. discovered a new type of two‐dimensional transition metal carbides and nitrides, called MXenes, which have become dazzling star in the energy storage industry. MXenes are endowed with series fascinating properties due to their unique structures tunable surface chemical functional groups. The application electrochemical has attracted special attention, especially showing great potential supercapacitor applications. Compared other materials, high mechanical flexibility, density, good performance, so they suitable as electrode materials for supercapacitors. However, similar 2D strong van der Waals forces, MXene layers inevitably undergo stacking agglomeration, resulting severe loss electrochemically active sites. If self‐stacking can be effectively suppressed, performance will enhanced. Structural optimization composite doping two strategies significant effects. This review summarizes recent advances synthesis, fundamental properties, focusing on latest MXene‐based electrodes/devices, puts forward challenges opportunities that face this emerging field.
