“…[ 63 ] On the basis of shear exfoliation, Antonatos et al changed the solvent to deoxygenated acetonitrile, which is a low‐boiling point solvent that can maintain a stable dispersion of 2D materials, can prevent the degradation of 2D materials from oxidation, and is easy to remove. [ 62 ] After the high‐energy shear force exfoliation process, high yields and stable colloidal solutions of gray and black arsenene nanosheets were achieved. Sturala et al introduced a photo‐assisted method using UV light irradiation and chromium hexacarbonyl to covalently functionalize and exfoliate gray arsenic crystals simultaneously.…”

“…The photothermal effect of 2D black and gray arsenic has also been investigated using 880 nm laser irradiation. [ 62 ] The temperatures of arsenic nanosheet dispersions with three different concentrations and pure water were then tested. All arsenic dispersions exhibited fast temperature increases in the first 5 min, while pure water showed negligible temperature fluctuations.…”

“…Moreover, impedimetric sensors based on the prepared 2D black and gray arsenene materials were also fabricated to detect volatile organic compounds (VOCs), demonstrating that 2D gray arsenic can be sensitive to methanol and ethanol and that 2D black arsenic can respond to five VOCs.

“…Mechanical exfoliation, liquid‐phase exfoliation, and chemical vapor deposition have been successively applied to obtain arsenene or 2D arsenic materials. [ 30,38,39,46,57–62 ] Benefiting from the development of preparation strategies, the potential applications and exotic properties of arsenene or 2D arsenic materials are largely promoted and studied.

Incorporating few‐layer 2D phosphorus–arsenic alloys (PAs) into optoelectronic devices requires a synthesis technique that allows control of the alloy composition while producing volumes of material suitable for application development such as photodetectors, solar cells, and lasers. With that goal in mind, high‐energy ball milling allows production of both orthorhombic (o‐PAs) and trigonal (t‐PAs) alloys by reacting red phosphorus and metallic arsenic powders. The synthesis follows a two‐step process in which arsenic rapidly reacts with red phosphorus to first produce t‐PAs followed by a slower phase transformation into o‐PAs; synthesis time and overall conversion rate are slightly enhanced by the presence of arsenic. Optical measurements on exfoliated alloys at the few‐layer atomic limit of the 2D PAs reveal emission spanning from the visible (≈1.9 eV) into the near‐infrared region, covering a broad application space. Rapid powder synthesis within a closed system for stochiometric control of the solid‐solution PAs alloys combined with solution‐based exfoliation opens up opportunities for a whole new class of optoelectronic devices based on PA nanomaterials.

Recent studies dedicated to layered van der Waals crystals have attracted significant attention to magnetic atomically thin crystals offering unprecedented opportunities for applications in innovative magnetoelectric, magneto‐optic, and spintronic devices. The active search for original platforms for the low‐dimensional magnetism study has emphasized the entirely new magnetic properties of two dimensional (2D) semiconductor CrSBr. Herein, for the first time, the electrochemical exfoliation of bulk CrSBr in a non‐aqueous environment is demonstrated. Notably, crystal cleavage governed by the structural anisotropy occurred along two directions forming atomically thin and few‐layered nanoribbons. The exfoliated material possesses an orthorhombic crystalline structure and strong optical anisotropy, showing the polarization dependencies of Raman signals. The antiferromagnetism exhibited by multilayered CrSBr gives precedence to ferromagnetic ordering in the revealed CrSBr nanostructures. Furthermore, the potential application of CrSBr nanoribbons is pioneered for electrochemical photodetector fabrication and demonstrates its responsivity up to 30 µA cm−2 in the visible spectrum. Moreover, the CrSBr‐based anode for lithium‐ion batteries exhibited high performance and self‐improving abilities. This anticipates that the results will pave the way toward the future study of CrSBr and practical applications in magneto‐ and optoelectronics.
