The urgent need for effective and sustainable electrocatalytic nitrate reduction to mitigate global water contamination and foster fossil-free ammonia generation has driven extensive exploration of bimetallic non-noble metals in electrochemical applications. Herein, we present the development of an electrocatalyst, namely FeCu phosphide (Fe–CuP), which demonstrates high efficiency in the reduction of nitrate. The prepared samples exhibit exceptional catalytic activity in the electrocatalytic reduction of nitrate to NH 3in a neutral electrolyte. It is noteworthy that the Faraday efficiency reaches an impressive 89% at −1.5 V ( vs. SCE), with NH 3
