Use of infrared spectroscopy in semiconductor photocatalysis
In the domain of semiconductor photocatalysis,infrared spectroscopy can provide information inter alia upon:-the scavenging of the photogenerated charges;-the surface radicals existing during or after irradiation;-the UV-irradiation effects on the water-surface interactions;-surface species not observed in the fluid phase;-the texture,structure and surface properties of photocatalysts and photocatalytic coatings.In practice,the challenges are to achieve conditions close to those of the photocatalytic reactions and satisfactory irradiation of the photocatalyst by both the exciting photons and the infrared beam.Labeled molecules can be employed to ascertain the bands attributions.Time-resolved experiments can be extremely useful.Examples will be presented.
