Efficient catalysts for hydrogen generation from seawater are essential for advancing clean energy technologies. In this study, we present a straightforward method for producing Pt nanoparticles enclosed within metallic 1T-phase MoS nanosheets on graphite paper as a promising catalyst for the hydrogen evolution reaction (HER). The resulting 14.3 wt % Pt-MoS nanosheets demonstrate an ultralow onset potential of 65.6 mV vs the reversible hydrogen electrode (RHE) and a minimal Tafel slope of 64 mV/dec with remarkable stability and durability in simulated seawater, offering comparable catalytic performance to the 40 wt % Pt/C commercial catalyst at a lower cost. This exceptional hydrogen production is attributed to the robust reducing ability of 1T-phase MoS and the confinement of Pt nanoparticles within the MoS interlayers and nanosheets. Our findings highlight the significance of this approach in developing practical and sustainable electrocatalysts for seawater splitting. This research represents a crucial step toward a greener and more sustainable future, leveraging innovative catalyst design strategies for clean energy production.
