Abstract Hydrogen is one of the most desirable alternatives to fossil fuel due to its cleanliness, renewability and large energy density. Efficient and durable electrocatalyst toward hydrogen evolution reaction (HER) is an urgent need for the sustainable development and long-term environmental conservation. The noble metal(Pt/Ru/Ir) has a favorable performance for HER but the high price and the low reserve hinder its further application. Meanwhile, the non-noble metal electrocatalysts can hardly achieve a satisfactory stability and efficiency. Therefore, this paper reports a Ru embedded N-doped carbon framework material as low-noble metal catalyst which has low loading of Ru (0.39 wt%) and exhibits the desirable overpotential of 181 mV at 10 mA cm−2 in alkaline and 298 mV at 10 mA cm−2 in acidic solution. Besides, it retains 94. 1% current density after durability potentiostatic tests for 30,000 s while the commercial 20 wt% Pt/C can only retain 84. 2%, which suggests a superior stability.

一锅法合成钌纳米粒子嵌入氮掺杂碳骨架用于电催化析氢反应

摘要 氢因其清洁、可再生和能量密度大而成为化石燃料最理想的替代品之一。高效耐用的析氢反应（HER）电催化剂是可持续发展和长期环境保护的迫切需要。贵金属(Pt/Ru/Ir)具有良好的HER性能，但价格高、储量低阻碍了其进一步应用。同时，非贵金属电催化剂难以达到令人满意的稳定性和效率。因此，本文报道了一种嵌入 Ru 的 N 掺杂碳骨架材料作为低贵金属催化剂，它具有低的 Ru 负载量（0.39 wt%），并在碱性和 298 mV 的 10 mA cm-2 下表现出理想的 181 mV 过电位。在 10 mA cm−2 的酸性溶液中。此外，它保留了94。
