Reengineered Vitamin B12 for Selective Aqueous Nitrate-to-Ammonium Electrocatalysis via Axial-Ligand Gating

Abstract Vitamin B12 (cobalamin) is an evolutionarily optimized Co-corrin redox cofactor capable of accessing low-valent cobalt states to mediate challenging biological transformations. Here, we reengineer this biological redox platform into an electrode-addressable catalyst for...
