Erbium‐Induced Interfacial Adsorption Regulation on Copper Enables Efficient Nitrite‐CO2 Coupling for Sustainable Electrochemical Urea Synthesis
Industrial wastewater rich in nitrite and anthropogenic CO2 emissions are typically treated as separate waste streams, requiring energy‐intensive management. Here we report an electrochemical strategy that couples nitrite and carbon dioxide to synthesize urea, enabling simultaneous pollution mitigation and resource rec...
