Microscopy of structured electrodes after the catalytic testing. a Pre- and post-reaction AFM analysis over a representative In2O3/Cu2O electrode (d = 1.25 μm) and corresponding profiles across two adjacent islands. Analysed area ca. 7.2 μm × 7.2 μm. The colour scale is associated to nanometres. b Representative post-reaction SEM micrographs for different Cu-In compositions. The interior of the islands is distinguishable by the presence of white particles. The top left image shows the centre of and island. Scale bars: 100 nm
