Foreword Saving the planet has become a popular topic among chemistry students and faculty alike. Individual steps of the water splitting reaction have been extensively studied at the interfaces of carbon-based nanostructures, notorious for corroding fast, and of noble metal particles, the cost of which is redhibitory for large-scale applications. In this context, Sandra Haschke's materials choice appears all the more consequent and bold: her Master's thesis is dedicated to iron(III) oxide, 'rust', as a platform for electrochemical water oxidation, the kinetic bottleneck of the overall water splitting. Indeed, iron(III) oxide provides the advantages of wide availability and low cost, as well as thermodynamic stability, two aspects of crucial practical importance. The impediments associated with iron(III) oxide, however, are of fundamental nature: low e
