Guys please I need your help..
In article: “The enhancement of photodegradation efficiency using Pt–TiO2 catalyst” F.B. Li, X.Z. Li Chemosphere 48 (2002) 1103–1111
Preparation of photocatalysts.
Photoreduction process: TiO2 was suspended in a mixture of hexachloroplatinic acid in methanol. The suspension was irradiated with a 125 W mercury lamp (60 min.). Pt-TiO2 was separated by filtration, washed with distilled water and dried at 100°C for 24 h.
why do we use methanol solvent and not use water in Preparation for doped Pt/TiO2?
what is the effect of using it?
And why the suspension irradiated with UV light .
what is the effect of using it?
Thank you in advance
