Low Price, High Purity Molybdenum Disulfide (MoS2) Powder

Used in thermoelectric-devices, sensors, LEDs, OPVs, and energy storage devices


Molybdenum disulfide (MoS2) possesses a sizeable intrinsic band-gap. It takes the form of a layered structure, in which crystalline planes are bound together by relatively weak Van der Waals forces. Its unique chemical, mechanical, and electronic properties make it widely used as a lubricant and a photocatalytic material.

Range of Applications

Used in thermoelectric-devices, sensors, LEDs, OPVs, and energy storage devices

As a 2D semiconducting material, MoS2 undergoes transformation from an indirect semiconductor in its bulk form (band-gap 1.2 eV) to a direct band-gap semiconductor (band-gap 1.9 eV) in its monolayer form. This makes MoS2 an ideal candidate in the fields of physics, chemistry, biochemistry, and electronic engineering. Advanced applications are also emerging in FETs, energy storage, gas sensors, and many other electronic and photo-electronic devices.

Molybdenum disulfide MoS2 powder is generally used to prepare MoS2 quantum dots solutions and nano-plateletes by liquid exfoliation assisted by sonication. MoS2 quantum dots have strong quantum confinement and edge effects. Thus, their direct-bandgap properties find applications in hydrogen evolution reactions (HER), photocatalytic hydrogen evolution, bioimaging and electrochemical lithium storage.

High-purity MoS2 powder can also be used in CV deposition to prepare high quality mono-layer films.

MoSpowder is obtained via the CVT method, with purity typically in excess of 99.995%.
