An Advanced Hierarchical MoS2/Mn for High Performance Hydrogen Evolution Reaction

Recently, molybdenum disulfide (MoS2) and other transition metal dichalcogenide (TMD) compounds represent a class of layered materials which have received tremendous attention due to their promising electronic, electrode material, catalytic, and mechanical properties. Currently, many researchers have investigated molybdenum disulfide (MoS2) which represents one of the most promising catalysts among TMDs due to the semiconducting nature and enhanced photoluminescence properties for hydrogen evolution. In this work, a systematic study of the relationship between the hydrogen evolution reaction (HER) and the physiochemical properties of layered MoS2 and doped derivatives has been performed. HER measurements with chemically modified MoS2 nanosheets were carried out using a three-electrode cell with a 0.5 M sulfuric acid electrolyte. All of the modified MoS2 nanosheets exhibit variation of overpotential catalytic activity towards the hydrogen evolution reaction. Taking into account this experimental result a configurational change will significantly enhance physical and chemical properties.
