摘要：
The photochemical activity of a prepared zirconium titanate, ZrTiO4, sample has been studied by laser flash photolysis. A short duration laser pulse was used to produce electron-hole pairs; methyl viologen was employed as electron scavenger. The same procedure has been employed to estimate the photochemical activity of two: home prepared single oxides, TiO2, (hp) and ZrO2 (hp) and for a commercially available TiO2, (Degussa, P-25). Our results further showed the potential of the laser flash photolysis technique to estimate the photosensitivity of semiconductor oxides and predict a poor photoactivity for the TiO2 (hp) sample in spite of this sample exhibiting (by XRD technique) the anatase as the unique phase.
