High quality and high purity MoSe2 Powder

Suitable for liquid chemical exfoliation

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.

Quasiparticle band-gap

With a high surface area and unique electronic (quasiparticle band-gap) properties, few-layered MoSe2 nanosheets have great potential as an advanced electrode material for supercapacitors and energy storage applications. Chemically-exfoliated MoSe2 nanosheets possess an obvious NIR absorption peak, leading to effective photothermal therapy of human lung cancer.

Applications of Molybdenum Diselenide Powder

MoSe2 powder is used in applications like photothermal therapy, biomedicine, energy storage devices, and electrocatalysts for hydrogen evolution reactions (HER).


Obtained via the CVT method, MoSepowder with purities of over 99.995% have been achieved.


MoSe2 powder is suitable for liquid chemical exfoliation to process MoSe2 quantum dot solutions and nano-plates down to few-layer films. High-quality, high-purity MoSe2 powder is also used for CV deposition of ultra-thin single or few-layer films.
