| Research Abstract |
The effect of energy level of conduction band edge on the photocatalytic activity for oxidative decomposition of organic compounds was investigated using tungsten-bismuth and molybdenum-bismuth mixed oxide particles as non-titania based photocatalysts. For bismuth tungstate, the photoinduced carrier dynamics was studied using time-resolved infrared absorption spectroscopy and the relation between the dynamics and photocatalytic activity was discussed. Alkali ion-modified silica-supported vanadium oxides were newly developed as a photocatalyst for photocatalytic oxidative decomposition of organic compounds.
