Electrocatalysis of the hydrogen evolution reaction (HER) is a promising route for sustainable hydrogen production based on water splitting. Designing MoP nanoparticles as catalysts is a feasible strategy to enhance the electrocatalytic performance for HER. In response, we report the fabrication of ultrafine MoP nanoparticles (NPs) which are uniformly embedded on glucose‐derived phosphorus and nitrogen co‐doped carbon nanosheets (MoP/NPG) as an effective electrocatalyst for HER via a novel and simple solid‐state reaction. Transmission electron microscopy reveals that the resulting product exhibits an average size of 3.15 nm. Due to the presence of exposed active sites in ultrafine MoP NPs and the laminar structure of carbon nanosheets, the MoP/NPS shows remarkable high catalytic activity having a low overpotential of 90 and 115 mV to achieve the current density of 10 mA cm⁻² in both, acidic and alkaline media, which demonstrates the promising potential for an application in sustainable energy production.

嵌入在碳纳米片中的超细MoP纳米粒子作为具有高活性位点密度的氢气产生的电催化剂

氢析出反应（HER）的电催化是一种基于水分解法可持续生产氢的有前途的途径。设计MoP纳米颗粒作为催化剂是增强HER电催化性能的可行策略。作为回应，我们报道了通过新颖且简单的固态反应将超细MoP纳米颗粒（NPs）均匀地嵌入葡萄糖衍生的磷和氮共掺杂碳纳米片（MoP / NPG）上的制造方法，作为HER的有效电催化剂。。透射电子显微镜显示，所得产物的平均尺寸为3.15nm。由于超细MoP NP中存在暴露的活性位点以及碳纳米片的层状结构，在酸性和碱性介质中均处于⁻²，这表明其在可持续能源生产中的应用前景广阔。
