Realizing efficient ammonia electrosynthesis enabled by metal–organic framework-derived CuCo-LDH

CuCo-layered double hydroxides derived from ZIF-67 facilitate nitrate electroreduction to ammonia with a yield of 7.27 mg h −1 cm −2 and a faradaic efficiency of 86.2%, maintaining stable operation for 120 h, and enabling the synthesis of (NH 4 ) 2 SO 4 .
