Water oxidation by a soluble iron(<scp>iii</scp>)–cyclen complex: new findings

Abstract

Herein, the role of iron oxide in the electrochemical water oxidation of an iron cyclen (cyclen = 1,4,7,10-tetraazacyclododecane) is considered using scanning electron microscopy, energy-dispersive spectrometry, X-ray diffraction, nuclear magnetic resonance spectroscopy, chronoamperometry, cyclic voltammetry and electrochemical impedance spectroscopy.
