Lattice Hydrogen Involved Electrocatalytic Nitrate Reduction to Hydroxylamine

Electrocatalytic nitrate reduction to hydroxylamine (ENRH) provides a sustainable strategy for NH2OH synthesis under ambient conditions. At present, active hydrogen (*H) derived from water dissociation has been widely used as a H-source for nitrate hydrogenation, bringing a big challenge for ENRH. On the one hand, insufficient *H would lead to the accumulation of nitrite. On the other hand, sufficient *H with high reduction ability would induce over-hydrogenation of hydroxylamine to ammonia. To overcome this challenge, herein, we propose to utilize lattice hydrogen (Hlat) with an appropriate reduction ability as the H-source for ENRH. We design and construct a Cu-MnO2Hx electrocatalyst, in which the…
