Photocatalytic Degradation of Poly(Vinyl Alcohol) on Pt/TiO sub(2) with Fenton Reagent

In this research Fenton reagent (Fe super(2+)/H sub(2)O sub(2)) was investigated as oxidants to degrade poly (vinyl alcohol) (PVA). The role of nano-TiO sub(2) photocatalyst was discussed as an additive in Fenton reagent (Fe super(2+)/H sub(2)O sub(2)). Pt/TiO sub(2) composites were also synthesized by photo-reaction to be used as additive in Fenton reagent. The rapid degradation of PVA was obtained when Pt/TiO sub(2) composites served as photocatalyst. The different photocatalytic efficiency of Pt/TiO sub(2)- Fenton reagent (Fe super(2+)/H sub(2)O sub(2)) was studied compared with TiO sub(2)- Fenton reagent (Fe super(2+)/H sub(2)O sub(2)) during the degradation of PVA.
