Doped Titania

A series of high surface area (~700 m2/g) nanostructured coupled semiconductor photocatalysts (NCSP) based on transition metals (M = Cr, V) doped titania-silica aerogel of various molar ratios of Ti:Si (1:25, 1:33 and 1:50) were synthesized via direct synthesis and wet impregnation methods. All samples reveal well-dispersed TiO2 with three different types of Ti coordination namely isolated Ti, non-isolated Ti and octahedrally coordinated Ti species. Cr and V (5 wt%)-titania silica aerogel under visible light irradiation reduced the bandgap energy of T25 to 2.9 eV. The photocatalytic activity of NCSP is 3 fold more active than photocatalyst supported on amorphous silica. Cr (5 wt%)-titania silica aerogel photocatalyst gives the highest conversion of styrene under both UV and visible light irradiation (55% and 47% respectively).

Doped Titania

The photodegradation of reactive green KE-4BD solution is investigated using N-doped titania (N-TiO2) under visible light irradiation. N-TiO2 is prepared using ammonia or urea as a nitrogen source and characterized by X-ray diffraction, Brunauer-Emmett-Teller methods, and UV-visible diffuse reflectance spectra. The effects of the initial dye concentration and pH on photocatalytic degradation are studied, and the direct correlation between pH, dye concentration, and the rate of degradation are determined. Experimental results show that aqueous solutions of KE-4BD degrade easily in weakly acidic conditions in the presence of N-doped TiO2 (1 g/L) as a photocatalyst. The optimized dye concentration for photolysis is 150 mg/L. The complete degradation of KE-4BD could be achieved under visible light irradiation, and the dye molecules could be partly decomposed into inorganic substances.
