Abstract:
Two N₅-chelated nickel complexes displayed decent catalytic activity and good stability for electrochemical water oxidation in phosphate buffer solutions at pH 7, with observed rate constants of 3.06 and 4.62 s⁻¹, which are higher than those reported so far for molecular nickel catalysts in neutral solutions. The results revealed that the rigid backbone of N₅-chelating ligands has a positive influence on the activity of the nickel catalysts.
