Triazolate-Functionalized Zirconium Nitride for Air-Fed H2O2 Production with Industrial-Level Current Density
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.
