“…X‐ray photoelectron spectroscopy (XPS) was employed to confirm the elemental composition and bonding of the ReS 2 NWs (Figure S3, Supporting Information), and the results agreed well with those reported in the literature . The Raman spectrum (Figure S4, Supporting Information) revealed the typical peaks of ReS 2 corresponding to the in‐plane (E g ) and out‐of‐plane (A g ) vibrational modes because of the low crystal symmetry and the association of these modes with the fundamental Raman modes that are coupled to each other and to acoustic phonons .…”

Highly efficient photocatalytic hydrogen evolution (PHE) is highly desirable for addressing the global energy crisis and environmental problems. Although much attention has been given to electron-hole separation, ridding photocatalysts of poor efficiency remains challenging. Here, a two-electron catalytic reaction is developed by utilizing the distinct trion behavior of ReS and the efficient reduction of two H (2H + 2e → H ) is realized. Due to the monolayer-like structure of the catalyst, the free electrons in ReS can be captured by the tightly bound excitons to form trions consisting of two electrons and one hole. These trions can migrate to the surface and participate in the two-electron reaction at the abundant active sites. As expected, such a two-electron catalytic reaction endows ReS with a PHE rate of 13 mmol g h under visible light irradiation. Meanwhile, this reaction allows the typically poor PHE efficiency of pure transition metal dichalcogenides to be overcome. The proposed two-electron catalytic reaction provides a new approach to the design of photocatalysts for PHE.

Transition metal dichalcogenides (TMDs) are promising for spintronic devices owing to their spin-orbit coupling and loss of inversion symmetry. However, further development was obstructed by their intrinsic nonmagnetic property. Doping TMDs with non-metal light atoms has been predicted to be a good option to induce unexpected magnetic properties which remain rarely explored. Here, we utilize nitrogen doping to introduce magnetic domains into anisotropic ReS 2 , giving rise to a transition from nonmagnetic to tunable magnetic ordering. Both of the experimental and computational results confirmed that the N-doping in ReS 2 prefers to take place at the edge site than in-plane site. With controlled doping concentration, it exhibits a unique ferromagnetic-antiferromagnetic (FM-AFM) coupling. Assisted by theoretical calculations, we demonstrated that FM-AFM coupling presents a strong link to doping contents and doping sites. Wherein, the FM ordering mostly comes from N atoms and the AFM ordering originate from Re atoms. At the N-doping content of 4.24%, the saturated magnetization of N-doped ReS 2 reached the largest value of 2.1 emu g −1 at 2 K. Further altering the content to 6.64%, the saturated magnetization of N-doped ReS 2 decreases, but exhibits a distinct exchange bias (EB) phenomenon of around 200 Oe. With controlled N-doping concentrations, the intrinsic spin in ReS 2 could be well altered and resulted in distinct magnetism, presenting tremendous potential for spintronic devices in information storage.

“…Additionally, Medhekar et al introduced the analogous electrochemical method to effectively regulate photoluminescence of MoS 2 by controlling the quantity of intercalated Li + ions . Other than MoS 2 , Fu et al also made use of electrochemical lithiation to intercalate Li + into ReS 2 to realize an oriented self‐assembly process . The interlayer distance of the as‐prepared sample was expanded to 0.63 nm (Figure e), indicating the feasibility of the metal ion intercalation extended to other 2D materials.…”

The development of two‐dimensional (2D) materials is experiencing a renaissance since the adventure of graphene. 2D materials typically exhibit strong in‐plane covalent bonding and weak out‐of‐plane van der Waals interactions through the interlayer gap. Opening 2D materials is an effective way to alter the physical and chemical properties, such as band gap, conductivity, optical property, thermoelectric property, photovoltaic property and superconductivity. A larger interlayer distance means more accessible active sites for catalysis, an ion‐accessible surface in the interlayer space, which may greatly enhance the performance of 2D materials for energy conversion and storage. Moreover, opening 2D materials by intercalation can change the band filling state and the Fermi level. This review mainly focuses on the opening of 2D materials and their subsequent applications in energy conversion and storage fields, expecting to promote the development of such a new class of materials, namely expanded 2D materials. The exciting progresses of these expanded materials made in both energy conversion and storage devices including solar cells, thermoelectric devices, electrocatalyst, supercapacitors and rechargeable batteries, is presented and discussed in depth. Furthermore, prospects and further developments in these exciting fields of the expanded 2D materials are also commented.
