摘要：

In the pursuit of sustainable and clean energy sources, the development of efficient electrocatalysts for hydrogen evolution reaction has gained significant attention. In this work, we synthesized single-atom Fe-doped 1T MoS2 (sFe-1T/MoS2) nanosheets using a one-step hydrothermal method, harnessing the synergistic effects of iron- intercalation to enhance hydrogen production through an abundance of active sites. Notably, 10 at.% sFe-1T/MoS2 exhibited excellent hydrogen evolution reaction performance with a low onset potential of 190 mV and a Tafel slope of 55 mV/dec in acidic solution. High performance was also achieved in alkaline solutions. Additionally, these catalysts demonstrated excellent efficiency in seawater splitting. This work not only offers a cost-effective and scalable method for producing high-quality electrocatalysts but also sets a precedent for the application of this technology across various catalytic systems, marking a significant advancement in clean energy research.
