Abstract :
The sintered glass filters with 90–150 µm porosity were coated with titanium
oxide/silver composite. For deposition of titanium oxide, the filter was deep coated in
the titanium oxide sole. Subsequently the solution of silver nitrate in methanol was used
for silver deposition. The ultra violet (UV) radiation with 254 nm wave length was used
for reducing silver ions to metallic silver. The prepared filters were characterized by Xray diffraction and scanning electron microscopy. The photo-catalytic efficiency of
TiO2 and TiO2/Ag coated sintered glass filters was investigated for photocatalytic
decomposition of epichlorohydrin. The 67% of 1 and 20 mg/lit of epichlorohydrin
solution in ethanol was decomposed by TiO2 /Ag coated filter after 3 hours UVA
radiations.
