This study reports an investigation on the fabrication of MoS2/Ti3C2 MXene nanocomposites via a hydrothermal route. Based on the result, the composite exhibited 2D/2D flower-like MoS2 layers stacked on the surface of Ti3C2 MXene nanosheets. The integration of MoS2 and Ti3C2 MXene significantly enhances electrocatalytic activity of hydrogen evolution reaction in alkaline electrolytes. Electrochemical studies reveal that the MoS2/Ti3C2 MXene nanocomposites exhibits a low overpotential and Tafel slope values of 421 mV and 217 mV dec−1, respectively. Electrochemical impedance spectroscopy analysis also reveals a significantly reduced charge transfer resistance (Rct) of 1.66 kΩ for nanocomposite. Electrochemical surface area (ECSA) of the nanocomposite, estimated from the electrochemical double-layer capacitance (Cdl), is 0.127 mF cm−2. Notably, the MoS2/Ti3C2 MXene nanocomposites exhibits excellent long-term stability. These results demonstrate the significant capacity of MoS2/Ti3C2 MXene nanocomposite as a highly effective electrocatalyst for HER and its contribution to sustainable energy production.
