Hydroxyl radical yield of photocatalysts determined using Coumarin as a OH radical trap molecule. Visible light active photocatalysts compared to a standard P25 UV light absorbing material. A range of photocatalysts covering a broad range of band gaps were assessed. Degradation of 7-hydroxycoumarin as a by-product considered.
