Transition metal-based chalcogenides as electrocatalysts for overall water splitting in hydrogen energy production

The main and significant element in the energy system is hydrogen atom. In addition, electrochemical water splitting is among the most crucial approaches for displacing the extensively utilized petroleum and petroleum products. It is crucial to look for effective electro-catalysts to split the water molecule to produce hydrogen. Because of their good conductivity, distinctive outer shell electronic distribution, and various superficial structural nano-morphology, transition metal chalcogenides are very attractive as effective electrocatalysts for hydrogen production. Currently synthesized transition metal-built chalcogens (containing Sulfur, Selenium, and Tellurium) as efficient catalysts for general splitting of target water using hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), have been discussed in this review.
