An organic-inorganic hybrid polyoxoniobate decorated by a Co()-amine complex for electrocatalytic urea splitting
The overall energy efficiency of electrochemical systems is significantly reduced by the conventional anodic oxygen evolution reaction (OER). It is feasible to improve energy efficiency by replacing the OER with the urea oxidation reaction (UOR), which has a lower thermodynamic potential. An organic...
