1.Photocatalyst TiO2
Photocatalyst absorbs light and causes various chemical reactions. Metal oxide and sulfide are known for photocatalyst, and especially TiO2 is being widely commercialized due to high photocatalytic efficiency, chemical stability and wide range of application.
2.Reaction of TiO2 photocatalyst
Under the condition of light energy which is bigger than band-gap energy(under 380nm) of the TiO2, it occurs photo-oxidation, photo-reduction and hydrophilic reaction. This reactivity can be used for a variety of uses. For example, the dissolution of hazardous VOCs, the removal of...
