Water oxidation by a soluble iron(iii)–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.
