• of the mesoporous films to assist the photodegradation of rhodamine B in water was studied. As a result, two maxima in the photocatalytic activity were identified in the calcination temperature range of 550–850 °C, peaking at 700 °C and 790 °C, and the origin of this was investigated by using

• that, of all the various oxide films, the KLE derived mesoporous MgTa2O6 film possessed the highest activity in assisting the photodegradation of RhB in water. Interestingly, PIB6000-templated mesoporous MgTa2O6 thin film showed a very similar dye-degradation activity as compared with the KLE-templated

• prolongs the lifetime of the photogenerated pairs, thus increasing the number of holes that are able to diffuse all the way to the surface to be involved in the photodegradation reaction. Small grains are assumed to facilitate the photocatalytic reaction, as it takes less time for the photogenerated pairs
