Molybdenum Selenide Nanoparticles

Molybdenum selenide Nanoparticles

Molybdenum selenide nanoparticles were prepared using a hydrothermal method, and the morphology, structures of the as-prepared. MoSe2 Nanoparticles were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). In turn, the excellent dispersibility and biocompatibility of theMoSe2 Nanoparticles solution was verified by sedimentation experiments and MTT tests.

Applications

Energy Storage and Conversion:

Lithium-ion and Sodium-ion Batteries: MoSe₂ nanoparticles are used as anode materials in lithium-ion and sodium-ion batteries due to their high capacity for charge storage, good cycling stability, and fast charge/discharge rates. The unique layered structure of MoSe₂ allows for the reversible intercalation of lithium and sodium ions, improving the overall performance of these batteries.

Supercapacitors: MoSe₂ nanoparticles, with their high surface area and conductivity, are being explored as electrode materials for supercapacitors. These materials can deliver high energy and power densities, making them ideal for applications requiring rapid energy release and absorption.

Photovoltaic Devices: MoSe₂ is also investigated as a material for thin-film solar cells. It can be used as a semiconducting layer in photovoltaic devices due to its appropriate bandgap (around 1.5 eV), which is ideal for light absorption and conversion into electricity.

Catalysis:

Hydrogen Evolution Reaction (HER): MoSe₂ nanoparticles are studied as catalysts for the hydrogen evolution reaction (HER) in water splitting for hydrogen production. MoSe₂, particularly in its nanostructured form, shows good catalytic activity for HER, making it a potential material for renewable energy generation from water electrolysis.

Electrocatalysis and Fuel Cells: MoSe₂ nanoparticles are also explored for electrocatalytic applications in fuel cells, especially in reactions like the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). Their unique electronic structure enables them to serve as efficient catalysts for these critical reactions in electrochemical energy conversion.
