The molybdenum phosphide (MoP) nanoparticles supported by phosphorus and nitrogen co-doped carbon nanosheet (N, P–C) have been prepared through simple one-step calcination method. The composition and morphology of the prepared hybrids were further characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and so on. The characterization results prove that the annealing temperature plays an essential role in the fabrication of nanosheets morphology. All characterization results prove that the MoP nanoparticles were uniformly loaded on N,P–C nanosheets. As excepted, the unique nanosheet structure not only contributes to mass transfer and electron transfer, but also increases electrochemical surface area. The obtained MoP/N,P–C-900 composites exhibit excellent HER activity and long-time stability (η = 129 mV for reaching 10 mA cm⁻² and 10 h for successive testing), which is superior than many other non-precious metal electrocatalysts. The present work affords a promising strategy for designing novel HER electrocatalysts, which may be applied in storage systems and diverse energy conversion.

磷和氮共掺杂碳纳米片（N，P–C）负载的磷化钼（MoP）纳米粒子是通过简单的一步煅烧方法制备的。通过扫描电子显微镜（SEM），X射线衍射（XRD），透射电子显微镜（TEM），X射线光电子能谱（XPS）等进一步表征了所制备杂种的组成和形态。表征结果证明，退火温度在纳米片形态的制备中起着至关重要的作用。所有表征结果均证明MoP纳米颗粒均匀地负载在N，P–C纳米片上。除此之外，独特的纳米片结构不仅有助于传质和电子传递，而且还增加了电化学表面积。获得的MoP / N，^-2和10 h进行连续测试），优于许多其他非贵金属电催化剂。目前的工作为设计新型的HER电催化剂提供了一种有希望的策略，可将其应用于存储系统和各种能量转换中。
