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.

Lamellar transition‐metal dichalcogenides (MX2) have promising applications in electrochemical energy storage and conversion devices due to their two‐dimensional structure, ultrathin thickness, large interlayer distance, tunable bandgap, and transformable phase nature. Interlayer engineering of MX2 nanosheets with large specific surface area can modulate their electronic structures and interlayer distance as well as the intercalated foreign species, which is important for optimizing their performance in different devices. In this review, a summary on recent progress of MX2 nanosheets and the significance of their interlayer engineering is presented firstly. Synthesis of interlayer‐expanded MX2 nanosheets with various strategies is then discussed in detail. Emphasis is focused on their applications in rechargeable batteries, pseudocapacitors, hydrogen evolution reaction (HER) catalysis and treatments of environmental contaminants, demonstrating the importance of interlayer engineering on controlling performance of MX2. The current challenges of the interlayer‐expanded MX2 and outlooks for further advances are finally discussed.

Hybrid nanostructures composed of vertical graphene nanosheet (VGNS) and MoS 2 nano-leaves are synthesized by the chemical vapor deposition method followed by a solvothermal process. The unique three-dimensional nanostructures of MoS 2 /VGNS arranged in a vertically aligned manner can be easily constructed on various substrates, including Ni foam and graphite paper. Compared with MoS 2 /carbon black, MoS 2 /VGNS nanocomposites grown on Ni foam exhibit enhanced electrochemical performance as the anode material of lithium-ion batteries, delivering a specific capacity of 1277 mAh g − 1 at a current density of 100 mA g − 1 and a high first-cycle coulombic efficiency of 76.6%. Moreover, the MoS 2 /VGNS nanostructures also retain a capacity of 1109 mAh g − 1 after 100 cycles at a current density of 200 mA g − 1 , suggesting excellent cycling stability. In addition, when the MoS 2 /VGNS nanocomposites grown on graphite paper are applied in the hydrogen evolution reaction, a small Tafel slope of 41.3 mV dec − 1 and a large double-layer capacitance of 7.96 mF cm − 2 are obtained, which are among the best values achievable by MoS 2 -based hybrid structures. These results demonstrate the potential applications of MoS 2 /VGNS hybrid materials for energy conversion and storage and may open up a new avenue for the development of vertically aligned, multifunctional nanoarchitectures.
