The first utilization of nitrogen‐doped graphdiyne (NGDY) as an efficient catalytic promoter for hydrogen evolution reaction (HER) is reported. X‐ray powder diffraction and X‐ray photoelectron spectroscopy studies indicate the presence of strong interactions between NGDY and MoS₂, which should effectively facilitate the charge transport behavior and improvement of the HER kinetics. The creative hybridization of MoS₂ and NGDY endows such heterostructure with structural and compositional advantages for boosting the catalytic activity (low overpotential of 186 mV at 10 mA cm⁻² and Tafel slope of 63 mV dec⁻¹) and extraordinary stability (higher than all reported MoS₂‐based materials and even better than that of commercial Pt and almost all benchmarked electrocatalysts). All of the results not only demonstrate that NGDY can be used as an effective catalytic promoter for hydrogen production, but also provide new strategy for fabricating efficient water‐splitting electrodes.

二维N掺杂的Graphdiyne纳米层上MoS2纳米片的受控生长，以实现高度相关的节水效果

首次报道了氮掺杂的石墨二炔（NGDY）作为氢释放反应（HER）的有效催化促进剂。X射线粉末衍射和X射线光电子能谱研究表明NGDY和MoS ₂之间存在强相互作用，这应有效地促进电荷迁移行为并改善HER动力学。MoS ₂和NGDY的创造性杂交赋予这种异质结构以结构和组成优势，以提高催化活性（在10 mA cm ^-2时低186 mV的过电势和63 mV dec ^-1的Tafel斜率）和非凡的稳定性（高于所有标准）已报告MoS ₂的材料，甚至比市售Pt和几乎所有基准的电催化剂都更好）。所有结果不仅证明NGDY可以用作制氢的有效催化促进剂，而且还为制备高效的水分解电极提供了新的策略。
