📗 Transition metal dichalcogenides have been extensively studied during last two decades. These materials range from insulators to conductors and have a diversity of properties including charge density waves, superconductivity, activity and a rich intercalation chemistry. Tungsten Dichalcogenides find a wide range of applications in the field of catalysis and as a lubricant at high temperature and pressure.WTe2 has been widely used for solar energy conversion in Photoelectrochemical (PEC) solar cell due to small band gap and high chemical stability.
