A peak ammonia yield rate of 45.61 mg h−1 mg−1 is achieved using a heterostructured catalyst inspired by copper-type nitrite reductases.
This reaction achieved nearly 100% Faradaic efficiency when conducted at potentials above −0.5 V, showcasing its high selectivity.
Mechanistic studies reveal that the dual role of the NiFe phase enhances electron and hydrogen donation during nitrite reduction reactions.
This biomimetic approach for catalyst design may lead to advancements in electrocatalytic applications across various fields.
