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.

“…[ 4 ] At the same time, MoS 2 nanomaterials have also been shown to be effective for energy storage in electrochemical capacitors (supercapacitors) due to their large surface area for double-layer charge storage or much higher pseudocapacitance from the H + or Li + intercalation into the S-Mo-S stacked layers. [ 5,6,9 ] Therefore, in view of fuel production (HER) and energy-storage applications (supercapacitors), edge-oriented MoS 2 thin fi lms hold signifi cant promise, provided there are a high degrees of exposed edges.Concurrent with the advances in MoS 2 fi lms, self-assembled porous metal oxides have been anodically grown on metal substrates. These fi lms show high surface area and 3D open frameworks that enable effi cient mass transport, and they have been used in applications in electrochemical energy production and storage.…”

A simple method to fabricate edge-oriented MoS2 films with sponge-like morphologies is demonstrated. They are directly fabricated through the reaction of sulfur vapor with anodically formed Mo oxide sponge-like films on flexible Mo substrates. The edge-oriented MoS2 film delivers excellent hydrogen evolution reaction (HER) activity with enhanced kinetics and long-term cycling stability. The material also has superior energy-storage performance when working as a flexible, all-solid-state supercapacitor device.

Electrodes of rationally designed composite nanostructures can o®er many opportunities for the enhanced performance in electrochemical energy storage. This paper attempts to illustrate the design and production of NiMoO 4 /polypyrrole core-shell nanostructures on nickel foam to be used in supercapacitor via a facile hydrothermal and electrodeposition process. It has been veri¯ed that this novel nanoscale morphology has outstanding capacitive performances. While employed as electrodes in supercapacitors, the composite nanostructures showed remarkable electrochemical performances with a great areal capacitance (3.2 F/cm 2 at a current density of 5 mA/cm 2 ), and a signi¯cant cycle stability (80% capacitance retention after 1000 cycles). The above results reveal that the composite nanostructures may be a likely electrode material for high-performance electrochemical capacitors.
