Over the past 20 years, transition metal dichalcogenides have been the subject of intense research. These materials range in qualities from insulators to conductors, and they feature a wide variety of intercalation chemistry, superconductivity, charge density waves, and activity. Molybdenum dichalcogenides are used in a variety of catalytic processes and as lubricants under extreme conditions of heat and pressure. Due to its narrow band gap and good chemical stability, MoSe2 has been extensively used in Photoelectrochemical (PEC) solar cells for the conversion of solar energy.

Transition metal dichalcogenide is a family of thin semiconducting materials in the form of MX2 in which M represents the transition metals molybdenum (Mo), tungsten (W), vanadium (V), etc. and X represents chalcogen atoms sulphur (S), selenium (Se), tellurium (Te). The transition metal layer is sandwiched between layers of chalcogen atoms. By virtue of excellent electrical and chemical properties, high mobility of charge carriers, low-power consumption, high flexibility and stretchability, lightweight, good mechanical robustness, and environmental stability, these materials proved themselves...
