Preparation self decontamination paint bosom photocatalytical composition TiO2/Ag

Recent studies to solve environmental pollution problems are directed to self decontaminating films. The most important and applicable mechanism is useing photocatalytical procedure. In this study, TiO2/Ag dye composite was synthesized by liquid impregnation method from two prime structures of titanium dioxide (anatase and rutile), with 2% of silver nitrate. The composite was characterized by SEM-EDX and UV-Vis. To determine the accuracy of the composite potential to decompose the pollutant in visible region, a halogen lamp of 100 W was used to degrade 1 mg/L of Rh.B. The result was 60% degredation of Rh.B within 240 min. Dispersion of nano-composite TiO2/Ag in acrylic semi-gloss paint business coatings was conducted by SEM. The results indicated that 100 mg/L Rh.B on the surface of dye containing TiO2/Ag composite was 40% degraded after 6 h illumination under 100 W halogen lamp.
