Electrocatalytic nitrogen reduction reaction provides sustainable environment-friendly process for ambient ammonia synthesis, and the development of highly active electrocatalysts is the critical topic. Herein, palladium hydride nanorods (PdH_0.43 NRs) are synthetized for electrochemical ammonia synthesis via the hydrogenation of Pd NRs with N,N-dimethylformamide. Due to the one-dimensional structure and enhanced nitrogen adsorption, PdH_0.43 NRs exhibit excellent NH₃ yield (17.53 mg h⁻¹ mg^-1_cat.), Faradaic efficiency (18.56%) and long-term electrochemical stability, superior to those of Pd NRs without hydrogenation. This hydrogenation strategy would offer an attractive strategy for the design of high-efficiency and robust metal hydrides for active NRR.

电催化氮还原反应为环境中的氨合成提供了可持续的环境友好方法，而高活性电催化剂的开发是关键课题。在此，合成钯氢化物纳米棒（PdH _0.43 NRs），用于通过用N，N-二甲基甲酰胺对Pd NRs进行氢化来电化学合成氨。由于一维结构和增强的氮吸附，PdH _0.43 NRs表现出优异的NH ₃收率（17.53 mg h ^-1 mg ^-1 _cat。），法拉第效率（18.56％）和长期电化学稳定性，优于未氢化的Pd NRs。这种氢化策略将为设计用于活性NRR的高效且坚固的金属氢化物提供有吸引力的策略。
