“…MXenes, known as two-dimensional transition metal carbides, nitrides, and/or carbonitrides, have a general formula of M n +1 X n T x ( n = 1, 2, 3), where M is the transition metal elements (M = Ti, Zr, Hf...), X stands for C and/or N, and T x represents the surface functional groups such as −O, −F, −OH, and so on. , The first MXene, Ti 3 C 2 T x , was discovered by Y. Gogotsi and M. W. Barsoum in 2011 by selecting etching Al from Ti 3 AlC 2 with hydrofluoric acid solution at room temperature. To date, more than 30 different configurations of MXenes have been successfully synthesized, while more than 100 potential compositions of MXenes have been predicted. , MXenes have excellent thermal stability, conductivity, photoelectric performance, mechanical performance, and theoretical storage capacity, − showing a variety of applications in sensing, photocatalysis, electromagnetic shielding, and energy storage. − …”

The structures of bare Ti3C2 and functionalized Ti3C2T2 (T = O, F, H, OH) MXenes were constructed, and the effect of surface functional groups T2 (T = O, F, H, OH) on the structural, electronic, and lithium storage properties were investigated by first-principles calculations. The results show that the proximity of surface functional groups will induce some lattice distortion of Ti3C2T2 MXene. The degree of lattice distortion depends mainly on the adsorption position of functional groups and the types of surface functional groups. From the point of view of forming energy, the surface functional groups tend to be located at the CCP site. From the energy band and DOS results, the presence of surface functional groups has a significant effect on the valence band, while it has a slight impact on the conduction band. In terms of lithium storage, lithium atom adsorption starts from the HCP position for bare Ti3C2, while functionalized Ti3C2T2 starts from the CCP position. The double-layer lithium storage capacity of bare Ti3C2 and Ti3C2O2 were 639.78 mAh/g and 537.22 mAh/g, respectively. And the single-layer lithium storage capacity of Ti3C2F2 was 130.77 mAh/g.

“…In addition, MXene has a high specific surface area and mechanical flexibility. Owing to its diverse characteristics, MXene can be suitably applied in electromagnetic interference (EMI) shielding and microwave absorption [ 20 , 21 ], sensors [ 22 ], energy storage [ 23 ], flame retardants [ 24 ], catalysis [ 25 ], adsorption [ 26 ], biomedicine [ 27 ], and other areas.…”

Two-dimensional (2D) transition-metal carbon/nitrogen/carbon nitride (MXene) has extremely high conductivity and easily modifiable surface functional groups. Compared with graphene, another 2D layered material, MXene is easily dispersed in water owing to its hydrophilic groups. Its unique characteristics make MXene a valuable material. Nanocomposites can be endowed with functionality when MXene is compounded with an elastomer. Particularly in electromagnetic interference shielding and sensing, MXene exhibits extraordinary properties. We review various preparation methods, properties, and applications of MXene and MXene/elastomer nanocomposites and present a summary of the prospects for MXene/elastomer nanocomposites, which are in their initial stage of development and providing promising results.

“…Moreover, Ti 3 C 2 T x MXene could also be a better coating material since its unique morphology, large specific surface, and abundant active sites, which warrant a strong affinity for polar or ionic species. Ghaemmaghami et al prepared Ti 3 C 2 T x based SPME coating via gluing method and utilized it for the analysis of PAHs in water, showing its excellent stability and good reproducibility [20]. However, the further expansion of the Ti 3 C 2 T x based SPME coating and its applications in the pretreatment technology remain attractive.…”

In this study, a new Ti 3 C 2 T x -coated fiber was synthesized and utilized as coatings for solid-phase microextraction of seven polychlorinated biphenyls. The as-produced multilayered Ti 3 C 2 T x MXene was characterized by X-ray diffractometer, thermos-gravimetric analysis, scanning electron microscopy, and energy dispersive spectroscopy. It is noteworthy that the Ti 3 C 2 T x showed some attractive features including unique 2D layered structures, large surface area, good hydrophilicity, and rich active recognition sites, endowing it has a high affinity towards the target polychlorinated biphenyls. Subsequently, the affecting parameters on the extraction efficiency of polychlorinated biphenyls were optimized. Under the optimal conditions, a novel method for the analysis of polychlorinated biphenyls in water samples was proposed. The Ti 3 C 2 T x -coated fiberbased solid-phase microextraction method showed good linearity (r 2 > 0.9928), high enrichment factors (268-442), low limits of detection (0.06-0.15 ng/L), and satisfactory repeatability (RSDs < 7.5%) for the polychlorinated biphenyls. The excellent method recoveries were in the range of 90.0-98.4, 92.0-98.2, and 92.0-98.0% for river water, lake water, and tap water samples, respectively. These results suggested that the proposed Ti 3 C 2 T x -coated fiber-based method represents a promising alternative for the analysis of polychlorinated biphenyls.
