MXene as Emerging Low Dimensional Material in Modern Energy and Bio Application: A Review

Abstract

MXene is a recently emerged two dimensional (2D) layered materials, a novel series of transition metal carbides, nitrides and carbonitrides were established by a group of scientists from Drexel University in 2011. Multi-layered MXene nanomaterials have been synthesized using different wet chemistry etching approaches. To date, around twenty different types of MXenes are synthesized using different wet chemistry etching techniques. To ensure reproducibility of the MXene, advanced characterizations in terms of morphology, structure as well as elemental compositions of the MXene flakes are conducted. MXenes nanosheets possess a significant thermo-electrical conductivity, reasonable band gap and high intrinsic carrier mobilities. The family materials of the MXenes have high potential for making energy storage devices such as batteries and supercapacitors as well as several many other implications such as electromagnetic interference shielding and capacitive desalination. MXenes are the potential candidates for hydrogen storage due to the interactive nature of hydrogen and these layered-structure materials. MXenes in biomedical applications were proven as valuable materials due to the tunable physiochemical properties into new distinct structures which is difficult to be manipulated in bulk materials. Besides, MXenes possess suitability of functionalization for tuning the various required properties for the specific properties. The many potential properties of MXene have disclosed new possibility to address the current need of higher efficiency materials for different applications.
