Аннотация: The dependence of action spectra for pristine and Cu-grafted anatase TiO₂ on temperature for photocatalytic acetone vapor oxidation at 40, 100 and 140 °C is described. The results obtained demonstrate the thermal inhibition of activity under UV irradiation for pristine titania at 140 °C, while for TiO₂ grafted with copper species this inhibition is suppressed. Photonic efficiency of visible radiation energy utilization by Cu-grafted titania increases with temperature and exceeds the corresponding value for pure anatase in the investigated temperature range.

Ключевые слова: TiO₂ photocatalysis, copper, grafting, oxidation, action spectra, thermal activation.
