The metastable 1T′ polymorph of MoS2 is an excellent catalyst toward the hydrogen evolution reaction. However, its production is limited by its lower energetic stability compared to the semiconductor 2H MoS2 phase. Stabilization of the 1T′ polymorph can be achieved through intercalation of sulfur‐based compounds without adversely affecting its catalytic properties.
Abstract
The metastable 1T′ polymorph of molybdenum disulfide (MoS2) has shown excellent catalytic activity toward the hydrogen evolution reaction (HER) in water‐splitting applications. Its basal plane exhibits high catalytic activity comparable to the edges in 2H MoS2 and noble metal platinum. However, the production and application of this polymorph are limited by its lower energetic stability compared to the semiconducting 2H MoS2 phase. Here, the production of stable intercalated 1T′ MoS2 nanosheets attached on graphitic nanoribbons is reported. The intercalated 1T′ MoS2 exhibits a stoichiometric S:Mo ratio of 2.3 (±0.1):1 with an expanded interlayer distance of 10 Å caused by a sulfur‐rich intercalation agent and is stable at room temperature for several months even after drying. The composition, structure, and catalytic activity toward HER are investigated both experimentally and theoretically. It is concluded that the 1T′ MoS2 phase is stabilized by the intercalated agents, which further improves the basal planes′ catalytic activity toward HER.

van der Waals heterostructures are demonstrated as building blocks for photonics and optoelectronics. Herein, a sub‐bandgap photodetection at λ = 1550 nm based on a MoSe2/WSe2 heterojunction is demonstrated. The high responsivity as well as high normalized photocurrent‐to‐dark current ratio indicate that the heterojunction device has promising applications in future optoelectronic.
Abstract
van der Waals (vdW) heterojunctions enable arbitrary combinations of different layered semiconductors with unique band structures, offering distinctive band engineering for photonic and optoelectronic devices with new functionalities and superior performance. Here, an interlayer photoresponse of a few‐layer MoSe2/WSe2 vdW heterojunction is reported. With proper electrical gating and bias, the heterojunction exhibits high‐sensitivity photodetection with the operation wavelength extended up to the telecommunication band (i.e. 1550 nm). The photoresponsivity and normalized photocurrent‐to‐dark current ratio reach up to 127 mA W−1 and 1.9 × 104 mW−1, respectively. The results not only provide a promising solution to realize high‐performance vdW telecommunication band photodetectors, but also pave the way for using sub‐bandgap engineering of two‐dimensional layered materials for photonic and optoelectronic applications.

2D distorted octahedral (1T') ReS2‐ReSe2 lateral heterojunctions with atomically sharp interfaces are synthesized by using two‐step epitaxial growth. Diverse interface structures and polarization‐sensitive photodiode properties are achieved in the 1T' heterojunctions, which open up new prospects for transition‐metal dichalcogenides in building multi‐functional electronic and optoelectronic devices.
Abstract
Creating heterojunctions between different 2D transition‐metal dichalcogenides (TMDs) would enable on‐demand tuning of electronic and optoelectronic properties in this new class of materials. However, the studies to date are mainly focused on hexagonal (2H) structure TMD‐based heterojunctions, and little attention is paid on the distorted octahedral (1T') structure TMD‐based heterojunctions. This study reports the large‐scale synthesis of monolayer 1T' ReS2‐ReSe2 lateral heterojunction with domain size up to 100 µm by using two‐step epitaxial growth. Atomic‐resolution scanning transmission electron microscopy reveals high crystal quality of the heterojunction with atomically sharp interfaces. Interestingly, three types of epitaxial growth modes accompanying formation of three different interface structures are revealed in the growth of 1T' heterojunction, where the angle between the b‐axis of ReS2 and ReSe2 is 0°, 120°, and 180°, respectively. The 0° and 180° interface structures are both found to be more abundant than the 120° interface structure owing to their relative lower formation energy. Electrical transport demonstrates that the as‐grown heterostructure forms lateral p–n junction with intrinsic rectification characteristics and exhibits polarization‐dependent photodiode properties. This is the first time the linear dichroism is achieved in 2D lateral heterostructure, which is important for the development of new devices with multi‐functionality.

Large‐scale 2D α‐In2Se3 nanosheets were prepared by a solvent exfoliation technique. The obtained α‐In2Se3 nanosheets exhibit excellent near‐infrared (NIR) photothermal performance under an 808 nm laser irradiation, which leads to a significant antibacterial effect. The excellent photothermal performance highlights the potential application in chemical and biological fields of α‐In2Se3 nanosheets.
Abstract
Two‐dimensional (2D) nanoflakes represent an appealing class of materials for optoelectronics applications due to their unique layered structures and excellent electronic properties. However, the lack of easy‐to‐manipulate and effective methods for large‐scale production of these 2D materials limits their potential for applications. Also, few efforts have been made to explore their applications in biological fields. This work reports the preparation of large quantities of 2D In2Se3 nanosheets through a solvent exfoliation technique. Transmission electron microscopy and atomic force microscopy results show that the In2Se3 nanosheets are obtained with lateral sizes of tens of nanometers to hundreds of nanometers and thickness of 2–17 layers. Raman features coupled with the X‐ray diffractometry results unequivocally confirm the as‐prepared In2Se3 nanosheets to be α phase. Moreover, these α‐In2Se3 nanosheets exhibit an excellent near‐infrared (NIR) photothermal performance under an 808 nm laser irradiation. NIR photo‐excitation of the α‐In2Se3 nanosheets in the presence of bacteria leads to a significant antibacterial effect, suggesting that these nanosheets have great potential to be photothermal antibacterial agents. Our work on α‐In2Se3 nanosheets presents an available method for exfoliating 2D layered materials, and highlights the potential application in chemical and biological fields of α‐In2Se3 nanosheets.

Molecular Functionalization of Two‐Dimensional MoS2 Nanosheets
by Anastasios Stergiou,

Molybdenum disulfide nanosheets have attracted great scientific interest for their remarkable electronic and optical properties. Key points related with the exfoliation routes, the surface functionalization approaches and the impact on the electronic, optical, and light‐harvesting properties of those hybrid nanostructures are comprehensively discussed.
Abstract
Molybdenum disulfide (MoS2) nanosheets have attracted great scientific interest for their remarkable electronic and optical properties. During the last few years significant progress on exfoliation methods of such nanosheets allowed the development of surface functionalization in covalent or noncovalent fashion. Markedly, the chemical modification allows tailoring and tuning the optical and electronic characteristics of MoS2, opening new avenues for the potentiality of MoS2‐based hybrids in diverse technological fields. Physisorption of organic molecules onto MoS2 through the development of numerous van der Waals interactions is the most widely approach employed for the surface noncovalent immobilization of organic species onto MoS2 nanosheets. Conversely, developed strategies for the edge and in‐plane covalent functionalization of MoS2 mainly concern chemistry at S vacancies, direct C−S bond formation, and coordination of S edges at metal centers. Herein, we focus into the most representative molecular doping strategies and material designing of MoS2‐based hybrid nanostructures carrying photo‐ and/or electro‐active components. Key points related with the exfoliation routes, the surface functionalization approaches and their impact on the electronic properties of the functionalized nanosheets are comprehensively discussed, offering a toolbox for scientists of different disciplines interested in putting a step forward in the field of transition‐metal dichalcogenide‐based materials.
