Useful:

• Chemical Classes: Metals -> Metals, Inorganic Compounds
• Canonical SMILES: [Se]=[Mo]=[Se]
• Description: Chemical exfoliation is one of the the most suitable routes towards large-scale production of nano-particles and nano-sheets. Using?N-methyl pyrrolidone (NMP) as a solvent, molybdenum diselenide (MoSe2) quantum dots can be prepared via chemical exfoliation - directly from molybdenum diselenide bulk powder.
• Uses: Solid lubricant. Molybdenum chalcogenide thin film transitors for solar cells are a rapidly expanding area of research and molybdenum selenide compounds play an important role in this research. The layered nature of MoSe2 gives rise to several interesting applications such as field effect transistors ; piezoelectrics and substrates for self assembly

One-pot hydrothermal synthesis and selective etching method of a porous MoSe₂ sand rose-like structure for electrocatalytic hydrogen evolution reaction

10.1039/c7ra10001a

This research presents a method for synthesizing a porous Molybdenum selenide (MoSe2) structure with enhanced electrocatalytic performance for the hydrogen evolution reaction (HER). The authors used a one-pot hydrothermal synthesis to create a MoSe2@Cu2Se composite, which was then selectively etched to remove copper, resulting in a porous MoSe2 structure resembling sand roses. The porous MoSe2 exhibited superior HER activity in acidic conditions, with a small onset overpotential of -150 mV and maintained a low overpotential of 300 mV for a current density of 6 mA cm^-2 after 1000 cycles. The study highlights the importance of the 3D porous structure in increasing the active surface area and improving catalytic activity. The findings suggest that this method could be applied to create other efficient electrocatalysts for HER and potentially other applications.
