Upgrading of nitrate to hydrazine through cascading electrocatalytic ammonia production with controllable N-N coupling.

ABSTRACT: Nitrogen oxides (NO_x) play important roles in the nitrogen cycle system and serve as renewable nitrogen sources for the synthesis of value-added chemicals driven by clean electricity. However, it is challenging to achieve selective conversion of NO_x to multi-nitrogen products (e.g., N₂H₄) via precise construction of a single N-N bond. Herein, we propose a strategy for NO_x-to-N₂H₄ under ambient conditions, involving electrochemical NO_x upgrading to NH₃, followed by ketone-mediated NH₃ to N₂H₄. It can achieve an impressive overall NO_x-to-N₂H₄ selectivity of 88.7%. We elucidate mechanistic insights into the ketone-mediated N-N cou
