The conventional Haber‐Bosch process for industrial ammonia production from N 2 and H 2 is not only energy‐intensive but also releases a large amount of CO 2 . The electrocatalytic nitrogen reduction reaction (NRR) is regarded as a sustainable and environmentally‐benign alternative approach for NH 3 production under ambient conditions. In this communication, it is reported that Fe 2 O 3 nanorods act as an efficient electrocatalyst for the NRR. In 0.1 M Na 2 SO 4 , it attains a Faradic efficiency of 0.94 % and NH 3 yield of 15.9 μg h −1 mg −1 cat. at −0.8 V vs. reversible hydrogen electrode. Furthermore, this catalyst also shows good stability during electrolysis and recycling tests.
