Hard Lewis Acid Mo6+ Orchestrates N-End Urea Adsorption to Steer Highly Selective Nitrite Electrosynthesis.
Electrocatalytic urea oxidation reaction (UOR) offers a promising route for coupling wastewater remediation with nitrogen upgrading. However, the structural complexity of urea, containing both electron-donating (─NH2) and electron-withdrawing (C = O) groups, leads to multiple adsorption configurations, resulting in poo...
