Recent Progress on Two-Dimensional Materials

“…The first report on the mechanical cleavage of atomically thin single-crystalline carbon film, namely graphene, and its extraordinary transport properties by Geim, Novoselov and coworkers 1 in 2004 had ignited the resurgence of a class of fascinating functional nanomaterials, i.e., two-dimensional (2D) materials [2][3][4][5][6][7][8][9][10] . 2D materials now have been recognized as a type of nanomaterials which have a sheet-like morphology featuring with a large lateral size from hundreds of nanometers to tens of micrometers or even larger but a thickness in single or few atomic layer 2,3 .…”

Tunable fluorescent amino-functionalized Ti3C2Tx MXene quantum dots for ultrasensitive Fe3+ ion sensing

“…Moreover, the non-toxic nature of MQDs generally results in good biocompatibility, and they are therefore expected to provide clear and intuitive biological information as a remarkable bioimaging material. 43 The high PL emission of N-MQDs in extreme pH conditions gives them great potential for bioimaging in gastric acid or urine samples.…”

Potential of MXene-Based Heterostructures for Energy Conversion and Storage

“…Soon, the use of 2D materials will need to be further explored in relation to MXenes, including graphene, transition-metal oxides, transition-metal dichalcogenides (MoS 2 and WS 2 ), layered double hydroxides (LDHs), boron carbon nitride materials (h-BN, g-C 3 N 4 , and BCN), and monoelemental compounds (black phosphorus and bismuthine). As other emerging 2D materials, , a single MXene layer and interlaminar vertical MXene layer are urgently needed for further modification.…”
