Abstract
These alcohols interactions with TiO2 surface give alcoholates. However, their interactions with Pd-TiO2 and Cu-TiO2 do not yield alcoholates. Doped catalysts have progressively grown dark during the experiments, especially when N2 atmospheres were used. This colour change may be given by the reduction of metal oxides deposited on the catalyst surface. These different photocatalytic behaviours may be explained by means of the alcoholate interaction with the catalysts surfaces, their ability to scavenge photogenerated electrons and react with radicals formed from propan-1-ol and butan-1-ol.
