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, SandraHaschke'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.

A model electrode of well-defined geometry prepared by direct laser-induced decoration of nanoporous templates with Au–Ag@C nanoparticles

“…As a template system, 'anodic' alumina is selected as it provides not only ordered arrays of parallel, cylindrical pores but also the possibility of varying accurately their diameter and length (in the ranges of about 10-300 nm and 0.5-100 μm, respectively), and thereby, of performing systematic studies of geometric effects [25][26][27][28][29][30][31]. Decoration of anodic membranes with Au-Ag@C NPs is carried out with a laser-induced deposition technique developed for planar transparent or nontransparent substrates [32][33][34], and transferred here to structured templates.…”
