Preparation of samples For the preparation of titania sol, the titanyl sulphate TiOSO 4 · n H 2 O was used. The TiO 2 · n H 2 O suspensions were prepared in the two ways: (i) Titanyl

considered critically to assess what novelty is really brought since the field seems to have been saturated. The basic principles are well known. A semiconductor (in this case TiO 2 ) acts as sensitizer for light-induced redox processes. Absorption of a
