Figure 1: Mesocrystal photocatalyst for hydrogen and hydrogen peroxide production

Caption

A hematite mesocrystal is a superstructure of particles, each around 20 nanometers in size. The mesocrystals were doped with Sn2+ and Ti4+ which were thermally induced to diffuse, segregating to form a composite oxide (SnTiOx) layer. The tin (Sn) on the uppermost layer is oxidized and becomes tin oxide (SnO2).
