Incorporation of noble metal nanoparticles has been expected to assist an efficient charge separation of photogenerated charge carriers leading to promoting the photocatalytic activity of TiO2.Gold nanoparticle is particularly of interest because of its typical optical property, surface plasmon resonance, which has been considered to a key factor of an increase of photocatalytic activity of TiO2 in several aspects.Herein, weinvestigated photocatalytic decomposition of 1,4-dioxane in water using various Au/TiO2 powders. Particularly, we focused on the relationship between the intensity of surface plasmon absorption and photocatalytic activity.In addition, we extendedour studyto the kinetics of 1,4-dioxane photodegradation as a case study. |
