Polyaromatic cores for the exfoliation of popular 2D materials

Abstract

The employment of the solvent interfacial trapping method and two aromatic stabilizers allows obtaining dispersions of two-dimensional materials with high concentrations.

Characterization of emerging 2D materials after chemical functionalization

“…In all cases, the exfoliated 2D materials tend to aggregate due to van der Waals interactions between layers. 14–16 In addition, some of these nanomaterials are chemically unstable, namely BP, 17 silicene 18 or germanene, 19 which rapidly oxidize under ambient conditions. In the case of TMDCs, their modification is sometimes convenient to obtain suitable values for their implementation on optoelectronic devices.…”

Simultaneous exfoliation and functionalization of MoS2 with tetrapyridyl porphyrin

“…[24][25][26][27] Sodium cholate and sodium dodecyl sulfate, among other surfactants, have also been used as stabilizers for aqueous suspensions of different layered materials, [28][29][30] and the employment of small molecules like aromatic compounds allows obtaining dispersions also in water, THF, DMF, methanol and dichloromethane. [31][32][33] It is worth mentioning that usually long sonication times are employed to obtain exfoliated materials (4-72 hours) using LPE. With the aim to reduce time, simultaneous exfoliation and functionalization approaches (covalent 34,35 and noncovalent [36][37][38][39] ) have been developed.…”

g-C3N4-modified Zr-Fc MOFs as a novel photocatalysis-self-Fenton system toward the direct hydroxylation of benzene to phenol

“…At the same time, the band gap width of g-C 3 N 4 is about 2.7 eV, which can effectively absorb sunlight and also it has a stable structure under light conditions. 20 Therefore, the designed photocatalyst was expected to possess a better effect in the direct hydroxylation of benzene to phenol under visible light.…”
