Electrocatalytic water oxidation by a Ni(ii) salophen-type complex.

ABSTRACT: A new mononuclear Ni(ii) complex, NiL (1), was synthesized from the reaction of Ni(OAc)₂·4H₂O and salophen-type N₂O₂-donor ligand, H₂L (where H₂L = 2,2'-((1E,1'E)-((4-chloro-5-methyl-1,2-phenylene)bis(azanylylidene))bis(methanylylidene))diphenol), in ethanol. The obtained complex was characterized by elemental analysis, spectroscopic techniques and single crystal X-ray analysis. The complex was studied as a water oxidizing catalyst and its electrocatalytic activity in the water oxidation reaction was tested in 0.5 M of borate buffer at pH = 3, 7 and 11 in a typical three-electrode setup with a carbon paste electrode modified by complex 1 as a working electrode. The linear sweep voltammetry (LSV) curves indicate
