Sandra Haschke presents a strategy to enhance the Fe2O3 electrode performance by controlled
nanostructuring of the catalyst surface based on anodized aluminum oxide coated by means of
atomic layer deposition. Furthermore she investigates the influence of underlying conductive
layers and post-deposition annealing on the electrode performance and the associated changes in
morphology and chemical composition. Exploiting all effects combined delivers an increase in
steady-state water oxidation throughput by a factor of 2.5 with respect to planar electrodes.
