Introduction to MXenes: synthesis and characteristics

A transport channel-regulated MXene membrane via organic phosphonic acids for efficient water permeation

“…Two-dimensional transition metal carbides, nitrides, and carbonnitrides, known as MXenes, have experienced an avalanche of research advances in diverse applications, including energy storage, electrocatalysis, water treatment, to name a few. [1][2][3][4][5] Among them, titanium-based MXenes (Ti 3 C 2 T x ) are of particular interest for water purification in the postgraphene era, due to their favorable features of rich surface chemistry, excellent mechanical property, and environmentfriendly characteristics. [6][7][8][9][10][11] Pristine Ti 3 C 2 T x membrane with selective sieving of various metal ions and dye cations have been reported by Ren et al as the first attempt of MXene-based separation membrane.…”

MXenes and MXene-based materials for tissue engineering and regenerative medicine: recent advances

“…56 Bottom-up chemical vapor deposition and top-down wet etching tactics have been broadly developed for the synthesis of MXenes. 57 The wet etching technique can be applied to provide MXenes with high quality and the presence of terminations, causing the fabrication of MXenes with a basically hydrophilic nature. 58 As an example, Ti 3 C 2 T x MXene fabricated through wet etching Ti 3 AlC 2 was employed for designing a screen-printed electrode, which included a dialysis microfluidic chip for multicomponent direct/continuous monitoring of whole blood.…”

Recent Advances of Emerging 2D MXene for Stable and Dendrite‐Free Metal Anodes

“…[158,159] However, mechanical exfoliation of MAX phase is hardly possible due to the strong interlayer chemical bonds between M and A. [160] To date, a lot of synthesis strategies for MXene have been reported, which mainly contains etching by fluoride-based aqueous solutions (such as HF, LiF + HCl mixtures, and NH 4 HF 2 ), [161] electrochemical method, [162][163][164][165] alkali-assisted hydrothermal method, [166] water-free etching in polar organic solvents, [167] molten salt etching method, [168][169][170] salt-templated method, [171] thermal reduction method, [172] and chemical vapor deposition (CVD) method. [173]…”
