2D crystals are emerging new materials in multidisciplinary fields including condensed state physics, electronics, energy, environmental engineering, and biomedicine. To employ 2D crystals for practical applications, these nanoscale crystals need to be processed into macroscale materials, such as suspensions, fibers, films, and 3D macrostructures. Among these macromaterials, fibers are flexible, knittable, and easy to use, which can fully reflect the advantages of the structure and properties of 2D crystals. Therefore, the fabrication and application of 2D crystal–based fibers is of great importance for expanding the impact of 2D crystals. In this Review, 2D crystals that are successfully prepared are overviewed based on their composition of elements. Subsequently, methods for preparing 2D crystals, 2D crystals dispersions, and 2D crystal–based fibers are systematically introduced. Then, the applications of 2D crystal–based fibers, such as flexible electronic devices, high‐efficiency catalysis, and adsorption, are also discussed. Finally, the status‐of‐quo, perspectives, and future challenges of 2D crystal–based fibers are summarized. This Review provides directions and guidelines for developing new 2D crystal–based fibers and exploring their potentials in the fields of smart wearable devices.

and piezophototronics in low-dimensional wurtzite structure ZnO and GaN have been systematically studied. [8,9] The piezoresistive effect is that the band gap structure of the semiconductor can be changed by strain, which can modulate the transport behavior of materials. The piezoresistive effect have been investigated in low-dimensional materials such as silicon nanowire, [10] carbon nanotube, [11] and graphene. [12] The piezoresistive materials have been widely used for improving the transport properties of transistor and force sensor. [13] 2D materials have opened up unprecedented opportunities in the semiconductor industry, and have attracted significant attention due to their subnanometer size, unique structure, and unusual electronic properties offering future advancements in electronic, optoelectronic, sensor, catalysis, and energy field. [14][15][16] In 2012, the piezoelectric [17] and piezoresistive effects [18] were predicted in 2D transition metal dichalcogenides (TMDCs). Due to the piezoresistive effect, the band gap of 2D MoS 2 decrease with the increase of strain, the direct band gap of monolayer TMDCs change to indirect band gap when the stain is 1-2% and the semiconductor TMDC became a conductor when the strain was over 10%. The piezoresistive effect was observed in photo luminescence (PL) spectrum subsequently and the piezoresistive coefficient of 2D MoS 2 was measured. [19,20] The effect of strain on the transport behavior due to piezoresistive effect was investigated and the 2D MoS 2 piezoresistive tactile sensor was invented recently. [21,22] The breaking symmetry in specific lattice orientation of 2D TMDCs materials lead to the piezoelectric effect. In 2014, the piezoelectric effect was first observed in 2D MoS 2 flexible device and the piezoelectric coefficient of monolayer MoS 2 was measured by using an atomic force microscope apparatus. [23,24] The high sensitivity piezoelectric force sensor based on monolayer MoS 2 was also developed then. [25] The piezoelectric polarization charges generated by the piezoelectric effect can tune the Schottky barrier height (SBH) of a device and the electric field at the interface of a heterostructure, which can further improve the performance of optoelectronic. Recently, Wu et al. and Lin et al. utilized the piezoelectric effect to improve the properties of metal-MoS 2 photodetector and 2D MoS 2 /WSe 2 Van der Waals heterostructure. [26,27] However, study on taking advantage of the piezoelectric and piezoresistive effects simultaneously to improve the photoelectric performance of photodetector based on 2DThe mechanically stretchable 2D materials have attracted much interest for their potential applications in flexible electronics, as well as the possibility of strain-tuning their electronic and photoelectric performance through piezoelectric and piezoresistive effects. Piezoelectric and piezoresistive effects are observed in a flexible monolayer MoS 2 device and the effect of the strain on the photoelectric properties is investigated. The light-dark curre...

Hydrogen from electrocatalytic water splitting is a clean and renewable source of sustainable energy. Highly efficient electrocatalyst is of great importance for the low‐cost and large‐scale production of hydrogen. Effective electrocatalysts made of earth abundant elements such as element P have attracted extensive interest. Due to the attractive properties of black phosphorus (BP) including tunable physicochemical characteristics, unique in‐plane anisotropic structure, high charge‐carrier mobility, and large specific surface area, make it stand out from four allotropes. And the breakthrough in BP exfoliation enables it to be a promising 2D platform for designing flexible and versatile BP‐based materials. This review summarizes all these bulk BP, BP nanosheets, BP quantum dots (QDs) as well as BP‐based materials as efficient electrocatalysts in the last several years, with their synthesis methods and electrocatalytic properties for water splitting. Furthermore, some challenges and perspectives for the future development of BP‐based electrocatalysts have been briefly offered.
