The biogeochemical cycles of carbon and nitrogen are globally disturbed due to the intensive use fossil fuels fertilizers, which is reflected by accumulation dioxide in atmosphere nitrate water streams. co-electroreduction a promising low-carbon alternative for urea synthesis that would help reestablish both cycles. This Perspective highlights importance rational catalyst electrolyte engineering enable electrochemical synthesis. Although field has gained significant attention over past few years, fundamental research under well-defined conditions remains underexplored. We highlight investigating structure-sensitivity effects on C-N coupling through complementary situ spectroscopy online techniques. Model studies, including surface-sensitive investigations, will be crucial understand molecular mechanisms thus rationally design more efficient systems electrosynthesis, paving way their scalable industrial applications.
