<p>In this work we have synthesized few layered MoS₂ nanosheets and to boost the electrochemical hydrogen evolution reaction (HER) over as an electrocatalyst, in situ Ag nanoparticles are loaded uniformly on the sheets by using simple and one pot method of hydrothermal synthesis. The overpotential drop recorded in Ag/MoS₂ is almost double as compared to pristine MoS₂ which indicates that decoration of Ag has lowered the barrier energy of the HER reaction and increased the efficiency of catalyst. In turn, layered structure of MoS₂ provided the matrix for uniform loading of Ag nanoparticles. More importantly, lower Tafel value (74&#xa0;mV/dec), lower charge transfer resistance and increased electric double layer capacitance in 10 wt% Ag/MoS₂ clearly implies the enhanced HER performance as well as robust stability owing to improved interface between Ag and MoS₂ along with increased exposed active sites. Therefore, this work explicitly focuses on the study of in situ loading of Ag over MoS₂ which provided more accessibility to the active sites to elevate the HER activity.</p> Graphical Abstract <p></p>
