Electrochemical water oxidation catalyzed by a mononuclear cobalt complex of pentadentate ligand: the critical effect of borate anion

Electrochemical water oxidation catalyzed by a cobalt complex, [Co(N3Py2)(H2O)] (ClO4)2 (1) (N3Py2 = 2,5,8-trimethyl-1,9-bis(2-pyridyl)-2,5,8-triazanonane) is reported. The release of dioxygen (O2) occurs with moderate onset overpotential of 540 mV and...
