摘要

Ultraviolet light was used to irradiate hydrocarbons on TiO_2 thin film in high-resolution transmission electron microscopy (TEM). The hydrocarbon was decomposed by photocatalysis of titanium oxide. Reaction processes were studied by using an in situ TEM observation system which was newly constructed for the present study. For measuring photocatalytic activities, electron energy loss spectroscopy (EELS) was used. We developed a new TEM method for observing crystal structures of TiO_2 and quantifying photocatalytic activities concurrently. We succeeded in measuring the photodecomposition activity of hydrocarbons on TiO_2 films in a submicron area. The spatial resolutions of the present method were compared with those of other methods for measuring photocatalytic activity.
