Recent advances in MXenes: beyond Ti-only systems

Abstract

Since the first report on Ti3C2Tx in 2011, the number of reports on the 2D transition metal carbides and nitrides, known as MXenes, has increased rapidly. Most of the reports...

Review of Metal Sulfide-Based MXene Nanocomposites for Environmental Applications, Gas Sensing, Energy Storage, and Photothermal Therapy

“…For instance, Zr 3 C 2 T x MXene has demonstrated enhanced structural stability compared to Ti 3 C 2 T x (TCT), and Cr 2 N MXene exhibits ferromagnetic behavior in contrast to the antiferromagnetic TCT, and V 2 CT x possesses a greater capacity for lithium (Li) storage than TCT, and the lateral shell size and monolayer thickness of Nb 2 C MXene are smaller and therefore more favorable compared to TCT, suggesting that the composition and bonding within the monolayer play a crucial role in determining the chemical properties of MXenes. The slower decomposition rate of Nb 2 C MXene in water further supports this notion …”

Progress and Prospects of MXene-Based Hybrid Composites for Next-Generation Energy Technology

“…[27][28][29][30][31][32][33][34][35][36][37] MXenes have already shown their potential in several research areas, including hybrid materials, energy storage devices, electromagnetic interference shielding, and nanocomposites. [38][39][40][41] In parallel, brand-new fields are emerging where MXenes excel above other nanomaterials, such as tribology. The foundation of each technology is research on the type of material.…”

Large valley splitting induced by spin–orbit coupling effects in monolayer W2NSCl

“…MXenes are a family of transition metal carbides and nitrides that have attracted attention for their excellent properties. 20 Since the first report of Ti 3 C 2 T x in 2011, 21 there has been a rapid increase in the number of reports on theoretical predictions and experimental syntheses of M n +1 X n T x (M is a transition metal atom, X is a carbon/nitrogen atom, and T x is a halogen element). Recently, reports related to valley physics have appeared in MXene materials, e.g., Shuo Li and Junjie He et al found that 2D Janus Cr 2 COF MXenes can produce valley polarization, 22 and Lu, J. J. and Liu, R. et al found that Y 3 N 2 O 2 MXenes and La 3 N 2 O 2 MXenes have different values of valley polarization.…”
