Applications

Molybdenum Diselenide (MoSe₂) is a member of the family of transition metal dichalcogenides (TMDCs), which has recently gained considerable attention for various applications in electrochemical, photocatalytic, and optoelectronic systems. The layered structure of (MoSe₂) plus the size and electrical conductivity of Se provide a good opportunity for hosting counterions in electrochemical energy storage
systems such as lithium-ion and sodium-ion batteries. The unsaturated Se atoms at the edge and those at defective points or altered basal plane have superior electrocatalytic activity toward hydrogen evolution reaction (HER) and similar electrocatalytic reactions (e.g., in lithium–oxygen batteries). Furthermore, the tunable band gap of (MoSe₂) has made it a promising candidate for photocatalysis and photoelectrochemical solar cells.

We can offer monolayer, multilayer MoSe₂ film and Isolated MoSe₂ flakes on substrates, such as sapphire, Si, Si/SiO₂, quartz etc. Substrate size is also customizable. Please contact MSE Supplies if you need bulk pricing or customization.
