Abstract

The electrochemical two-electron oxygen reduction reaction (2e^– ORR) offers a green and energy-efficient pathway for hydrogen peroxide (H₂O₂) production, yet reliance on high-purity oxygen significantly limits scalability. Here, we report a triazolate-modified zirconium nitride catalyst (T-ZrN) that enables efficient and durable H₂O₂ electrosynthesis directly from atmospheric air. The T-ZrN catalyst achieves a high H₂O₂ yield of 55.6 mol·h^–1·g^–1 and a Faradaic efficiency of 93.2%, while maintaining stable operation over 540 h at an industrial-level current density of 800 mA·cm^–2. Economic analysis reveals a production cost of 70 wt % H₂O₂ as low as $0.10 kg^–1, highlighting its commercial potential. This work presents a viable strategy for cost-effective and decentralized H₂O₂ manufacturing advancing sustainable chemical production technologies.

三唑酸功能化氮化锆在工业级电流密度下气送H2O2生产中的应用。

电化学双电子氧还原反应（2e- ORR）为生产过氧化氢（H2O2）提供了一种绿色节能的途径，但对高纯度氧气的依赖严重限制了可扩展性。在这里，我们报道了一种三唑酸盐修饰的氮化锆催化剂（T-ZrN），它可以直接从大气中高效、持久地电合成H2O2。T-ZrN催化剂的H2O2产率为55.6 mol·h-1·g-1，法拉第效率为93.2%，在800 mA·cm-2的工业级电流密度下可稳定运行540 h以上。经济分析显示，70% H2O2的生产成本低至0.10美元/ kg-1，凸显了其商业潜力。这项工作提出了一个可行的战略，具有成本效益和分散的H2O2制造推进可持续化工生产技术。
