The layered molybdenum chalcogenide MoS 2 has attracted wide attention due to its potential electrochemical applications. Based on its unique physical and chemical properties, numerous advances have shown that nanostructured MoS 2 , with the advantages of low cost and outstanding properties, is a promising candidate for environmentally benign energy conversion and storage (ECS) devices.Nowadays, in order to lessen the reliance on fossil fuels, the production of hydrogen from water splitting has become an important issue. Hence, developing catalysts composed of earth-abundant elements that possess activities comparable to those of noble metals is of great urgency. According to DFT calculations in terms of HER free-energy diagrams, MoS 2 could be used as an effective substitute for noble metals. Meanwhile, MoS 2 with various structures has also been applied in the field of energy storage, including batteries and supercapacitors. Additionally, due to their layer-dependent electrical properties, MoS 2 -based electrochemical devices have been applied as sensors for a variety of chemicals.In this review, we summarize recent advances in the development of MoS 2 with high-performance in various electrochemical domains, and recent progress in discovering the mechanisms underlying the enhanced activity. Moreover, we summarize the critical obstacles facing MoS 2 , and discuss strategies for further improving its activity. Lastly, we offer some suggestions on the pathways toward achieving high performance competitive with noble metal counterparts, and perspectives on practical applications of MoS 2 in the future. Broader contextThe development of inexhaustible and clean energy technologies has far-reaching benefits for our society. Owing to its high anisotropy and unique crystal structure, the attractive properties of 2D molybdenum disulfide (MoS 2 ) can be utilized in a variety of energy conversion and storage (ECS) applications. Therefore, understanding how these properties can be tuned and the tunable properties can be utilized becomes increasingly important. In this review, we first summarize recent synthetic strategies toward preparation of MoS 2 with different structures, and its role in several important renewable energy technologies. We then discuss the relationship between the tuned properties and the performance of MoS 2 in different applications, emerging trends during their development, and challenges facing them, offering our perspectives on how to effectively advance the development of MoS 2 -based devices.

Abstract:A low-cost bio-mass-derived carbon substrate has been employed to synthesize MoS 2 @carbon composites through a hydrothermal method. Carbon fibers derived from natural cotton provide a three-dimensional and open framework for the uniform growth of MoS 2 nanosheets, thus hierarchically constructing coaxial architecture. The unique structure could synergistically benefit fast Li-ion and electron transport from the conductive carbon scaffold and porous MoS 2 nanostructures. As a result, the MoS 2 @carbon composites-when serving as anodes for Li-ion batteries-exhibit a high reversible specific capacity of 820 mAh·g −1 , high-rate capability (457 mAh·g −1 at 2 A·g −1 ), and excellent cycling stability. The use of bio-mass-derived carbon makes the MoS 2 @carbon composites low-cost and promising anode materials for high-performance Li-ion batteries.

“…Both experimental and theoretical studies have proved the application of monolayer MoS 2 as anode in SIBs, demonstrating a high theoretical capacity and fast diffusion kinetics. [29][30][31][32][33][34] [35] and Yang et al [36] predicted that the 1-D MoS 2 NRs were a promising host in rechargeable Li-ion batteries and Mg-ion batteries. In addition, MoS 2 NRs possess two advantages as anode in SIBs: Firstly, zigzag MoS 2 NRs display a metallic feature while the bulk and monolayer MoS 2 are semiconducting with the band gap of 1.29 and 1.80 eV, respectively.…”

Substantial effort has been made to search for electrode materials of Na-ion batteries with high energy/power density. The application of S-saturated zigzag MoS 2 nanoribbons (MoS 2 NRs) for Na-ion batteries has been explored through density function theory (DFT). The theoretical maximum specific capacity reaches 386.4 mAh•g 1 via double-side and special edge adsorption mode. The electronic structure reveals that there exists charge transfer between Na and MoS 2 NRs. The diffusion barrier on MoS 2 NRs (0.17 eV) is much lower than that of bulk MoS 2 (1.15 eV), indicating an excellent diffusion kinetics. In addition, the S-edge in MoS 2 NRs plays a key role. Firstly, the Mo edge was half saturated by S, which helps to stabilize the MoS 2 NRs as well as offer more intercalation sites for Na. On the other hand, Na migrates much faster on the S edge route in MoS 2 NRs. Our computational results show that S-saturated MoS 2 NRs exhibit a great potential as electrode materials for Na-ion batteries with high performance.
