The Synergetic Effect of MoSO2/Graphite Nanosheets as Highly Efficient for Electrochemical Water Splitting in Acidic Media

Metal oxide nanoarchitectures have a wide range of qualities that can be used to produce novel technologies in the field of renewable energy, such as energy conversion solar fuels and storage via the photovoltaic effect, and electrochemical water splitting. The approach for the synthesis of earth abundant metal oxide nanostructures is facile and cost effective and involves scalable methodologies for the development of functional devices. The composite material exhibits enhanced active edge sites for the potential HER. The electrochemical experiments revealed satisfactory results of electrocatalytic gas production HER. The composite sample produces a current density at 10 mAcm−2 an over potential of 345 mV and Tafel value of 60 mVdec−1 it exhibits at which predominantly ensures the swift charge transfer kinetics during HER. The sample 3 remains durable and stable for 30 hours. EIS shown value of 21.88 Ohms as charge transfer resistance which further strengthened HER and Tafel results. The sample 3 exhibits a 4.69 µFcm−2 capacitance double layer and surface area of 177.25 cm2 it further supports the unique productivity for HER activity. The small Tafel slope which relatively close to Pt shows a clear and high potential of as prepared MoS2/Graphite nanosheets composite material for the replacement of noble metals in the field of renewable energy. The tiny Tafel slope value suggests that the efficient hydrogen evolution reaction has a lot of promise. This developed method provides the alternative method for the development of other materials for the energy harvesting applications.
