Molybdenum Tungsten Disulfide (MoWS2) Powder

Applications of Molybdenum Disulfide Powder

With a tunable band gap, band edge position, and carriers’ effective mass, thin-layer nanosheets of MoWS₂ have applications in electrochemistry and possess superior hydrogen evolution reaction performance. It has also been used in the development of high-performance optical switching, Q-switching, mode-locking, optical limiting, and optoelectronic devices.

Synthesis

Molybdenum tungsten disulfide powder is obtained via the CVT method, with purity typically in excess of 99.995%.

Usage

Molybdenum tungsten disulfide powder is generally used to prepare MoWS₂ quantum dot solutions and nano-platelets by liquid exfoliation assisted by sonication. High-purity MoWS₂ powder can also be used in CV deposition to prepare high-quality monolayer films.
