Uniformly dispersed ∼10 nm MoP nanoparticles on N-doped carbon nanotube and graphene composite (NCNT-NGR) support are synthesized via a simple temperature-programmed reduction method for electrocatalytic hydrogen evolution reaction (HER). The NCNT-NGR support is composed of well-intercalated carbon nanotube (CNT) between graphene layers, resulting in suppressed CNT bundling and graphene re-stacking, hence providing a large surface area. The prepared MoP/NCNT-NGR composite exhibits high HER activity than control catalysts (MoP/NCNT, MoP/NGR, and bare MoP) with a small benchmark overpotential of 100 mV to drive 10 mA/cm² and an improved Tafel slope of 44 mV/dec in an acidic medium. It also exhibits excellent stability for 1000 potential cycles and in a 10-h chronoamperometry test. Such a HER performance arises from synergy between highly active MoP nanoparticles and the large surface area/highly conductive NCNT-NGR support.

通过简单的程序升温还原法，在电催化氢释放反应（HER）上，在N掺杂碳纳米管和石墨烯复合材料（NCNT-NGR）载体上合成了均匀分散的〜10 nm MoP纳米颗粒。NCNT-NGR载体由石墨烯层之间的插层良好的碳纳米管（CNT）组成，可抑制CNT的束缚和石墨烯的重新堆积，从而提供较大的表面积。制备的MoP / NCNT-NGR复合材料比对照催化剂（MoP / NCNT，MoP / NGR和裸MoP）具有更高的HER活性，具有100 mV的较小基准过电势，可驱动10 mA / cm ²在酸性介质中的Tafel斜率提高了44 mV / dec。在1000个潜在周期和10小时计时电流测试中，它还具有出色的稳定性。此类HER性能源自高活性MoP纳米颗粒与大表面积/高导电性NCNT-NGR载体之间的协同作用。
