Highly selective electrochemical reduction of nitrite to ammonia over CuWO 4 nanoparticles

CuWO 4 nanoparticles serve as a highly efficient electrocatalyst for the selective reduction of NO 2 − to NH 3 . In neutral solution, CuWO 4 achieves an NH 3 production rate of 27.46 mg h −1 cm −2 and a faradaic efficiency of 95.09% at −1.0 V.
