Molybdenum phosphide in transition metal phosphides members are considered as an attractive electrocatalyst for hydrogen evolution reaction (HER). However, its unsatisfactory stability and conductivity in an alkaline environment has dragged on its development. Here, we successfully introduced N, C co-doped MoP (MoP-NC) nanoparticles by a simple and efficient two-step synthesis method using urea as a carbon source into the molybdenum phosphide system. The cheapness of urea and the excellent carbon to nitrogen ratio remove the obstacles ahead of the development of MoP-NC composites. The obtained composites have excellent HER electrocatalytic activity and stability in 1-M potassium hydroxide (KOH) solution, which requires only an overpotential of 131 mV to achieve a current density of 10 mA cm-2 and exhibits negligible performance degradation after 1000 CV cycles.

高效合成碳基磷化钼纳米粒子用于电催化制氢。

过渡金属磷化物中的磷化钼被认为是氢释放反应（HER）的有吸引力的电催化剂。然而，其在碱性环境中的令人满意的稳定性和导电性拖延了其发展。在这里，我们通过简单有效的两步合成方法，以尿素为碳源，成功地将N，C共掺杂的MoP（MoP-NC）纳米颗粒引入了磷化钼体系。尿素的便宜性和出色的碳氮比消除了MoP-NC复合材料开发之前的障碍。所得复合材料在1-M氢氧化钾（KOH）溶液中具有优异的HER电催化活性和稳定性，
