Nitrogen Reduction: The vanadium atoms decorated ferric oxide (named as V-α-Fe₂O₃) with polyhedral-like structure was obtained by a simple one-step hydrothermal method. Benefited from the incorporation of vanadium atoms, the electronic structure and the active center of α-Fe₂O₃ were well-optimized, with enhanced NRR activity being obtained. The 17 % V-α-Fe₂O₃ exhibits excellent catalytic activity, with the NH₃ yield and the Faradaic efficiency (FE) being 68.7 μg h⁻¹ mg⁻¹_cat. and 5.7 % at −0.2 V (vs. RHE), respectively.

具有多面体结构的阳离子修饰氧化铁用于电催化氮还原反应

氮还原：通过简单的一步水热法获得具有多面体结构的钒原子装饰的氧化铁（命名为V-α-Fe ₂ O ₃）。受益于钒原子的掺入，α-Fe ₂ O ₃的电子结构和活性中心得到了很好的优化，获得了增强的NRR活性。17% V-α-Fe ₂ O ₃表现出优异的催化活性，NH ₃产率和法拉第效率（FE）为68.7 μg h ^-1  mg ^-1 _cat。-0.2 V（相对于 RHE）时分别为 5.7% 和 5.7%。
