Molybdenum Disulfide Electrocatalysts for Hydrogen Evolution and Energy Storage
This community develops molybdenum disulfide (MoS2) nanosheets and related transition metal dichalcogenides to serve as electrocatalysts for hydrogen production and as active materials for lithium-ion batteries and supercapacitors.
The work centers on engineering the crystal phase, defect structure, and surface chemistry of two-dimensional MoS2 to enhance its activity in the hydrogen evolution reaction. Researchers frequently combine MoS2 with carbon materials, such as graphene oxide or reduced graphene, to improve conductivity and stability. A significant portion of the literature addresses the synthesis of metallic-phase MoS2 nanosheets and the creation of heterostructures with other transition metal compounds. While hydrogen evolution is the dominant application, a substantial subset of papers investigates the use of these same materials for lithium storage and energy conversion, often exploring how phase engineering and edge-site activation influence performance in both electrochemical contexts.
Molybdenum research accounts for 3.7% of all tracked molybdenum studies, representing the largest share of this community’s output. Hydrogen research contributes 0.7% of its total volume, while lithium research accounts for 0.4%.
The community comprises 7,745 papers, with the highest publication volumes appearing in the International Journal of Hydrogen Energy, Applied Surface Science, and Electrochimica Acta.
Recent work continues to focus on scalable synthesis of pure-phase metallic MoS2 nanosheets and the engineering of defects and heterostructures to optimize alkaline water electrolysis and battery performance.
