Abstract The green urea synthesis via co‐electrolysis of waste nitrate and CO 2 is alluring but challenging, especially with insufficient selectivity caused by thermodynamic differences kinetic mismatch between multi‐step conversion processes. Here, a domino effect‐oriented electrosynthesis strategy showcased to steer cascade reactions in upgrading toward high on Bi‐doped In O 3 asymmetric oxygen vacancies (O v ). conventionally arbitrary reaction mode can be vectored re‐customized stable cumulative * NH intermediates situ derived from priority reduction reaction, which not only form surface frustrated Lewis pairs (SFLPs, Bi─O ─In─NH ) Bi acid sites synergistically adsorb activate also provide more opportunities for sluggish C─N coupling, delivering an unprecedented Faradic efficiency 80.2% impressive yield 2.38 × 10 µg h −1 mg cat. at −0.4 V versus RHE. atomically dispersed promote the protonation NO nucleophilic intermediates, stabilized electrophilic region mediated , permitting two attacks complete coupling. modeling protocol positioning specific intermediate tailors parallel process may guide control electrosynthesis.
