Recent Progress of Janus 2D Transition Metal Chalcogenides: From Theory to Experiments

“…There are numerous methods that can be used to fabricate 2D materials, such as micromechanical exfoliation, liquid exfoliation, CVD, and hydrothermal synthesis. [79][80][81][82] A series of 2D materials, such as graphene, h-BN, and TMD have been fabricated successfully via these means, [83][84][85][86][87] which has gradually realized the high quality and large-scale fabrication of 2D materials. However, the fabrication technology for the Janus 2D materials is not yet mature.…”

Electrochemically Exfoliated Black Phosphorus Nanosheets – Prospective Field Emitters

“…[2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] The field enhancement factor (β) depends upon the geometry of the emitter and the spatial distribution of the emitting centers. [22][23][24][25][26][27][28][29][30][31][32][33][34] Recently, intense research work has been carried out to explore the use of 2D inorganic nanomaterials as possible field emitters in view of their unique properties as compared to their bulk counterparts, such as large surface to volume ratio, high aspect ratio, possibility of facile surface functionalization, superior emission current stability of the emitter, and perfect crystallinity. This suggests that field emitter materials with elongated morphology and sharp edges/tips can have significantly enhanced FE properties in terms of reduction in the operating voltage and enhancement of the field emission current density.…”

Facile Synthesis of Molybdenum Disulfide/Carbon Nanocomposites in Polyacrylic Acid Hydrogel as Anode for Lithium‐Ion Batteries

“…[4,5] Metal sulfides represent an interesting class of electrode materials for LIBs because of their high abundance, low cost, and intriguing properties. [6][7][8] Molybdenum disulfide (MoS 2 ), a typical 2D material, is a promising anode material for LIBs because its theoretical capacity (669 mAh g À1 ) is three times that of graphite. [9] It has a welldefined layered structure with strong covalent bonding in each layer and weak Van der Waals forces between the layers.…”
