In the context of escalating environmental pollution and the persistent energy crisis, there is an increasing demand for new and clean energy sources. The subject of hydrogen energy has attracted extensive attention from the public because of its remarkably high energy density and zero-emission environmental characteristics. It is regarded as a potentially significant energy source, with the potential to displace fossil fuels in the future, thereby marking a new era in energy transformation and sustainable development. However, the lack of inexpensive, abundant, and high-performance electrocatalysts hinders the advancement of hydrogen energy. In this paper, we have synthesized MoSe 2 by hydrothermal method and subsequently prepared phosphorusdoped MoSe 2 (P-MoSe 2 ) by phosphorization treatment. The P-MoSe 2 catalyst prepared in this study demonstrated excellent hydrogen evolution performance in an alkaline environment. At the prevailing current density of 10 mA·cm -2 , the catalyst demonstrated superior performance, exhibiting an overpotential of 173 mV and the Tafel slope was determined to be 88.91 mV/dec -1 . This finding provides novel insights and avenues for the exploration of new types of hydrogen evolution catalysts, thereby facilitating technical progress and practical applications in this field.
