Synthesis, characterization and photocatalytic properties of iron-doped titania semiconductors prepared from TiO2 and iron(III) acetylacetonate

Oxalic acid destruction at high concentrations by combined heterogeneous photocatalysis and photo-Fenton processes

“…This has been used to explain the small but detectable degradation of oxalic acid under visible irradiation, which does not occur on bare titania but does take place with Fedoped TiO 2 photocatalysts [54].…”

E. coli inactivation by visible light irradiation using a Fe–Cd/TiO 2 photocatalyst: Statistical analysis and optimization of operating parameters

“…Fe-Cd/TiO 2 (2% Cd, 3% Fe molar ratio) was synthesized using a sol-gel method. The specific molar ratios of the dopants were selected in accordance with optimized activity as reported in our and previous studies [33][34][35][36][37]. In this method, 2.5 mL titanium isopropoxide (TTIP, ≥98%, Sigma-Aldrich) was added into 4.3 mL glacial acetic acid (Merck KgaA, Darmstadt, Germany), and the mixture was stirred vigorously in an ice bath (0 • C) for 30 min, during which time a sol was formed.…”

Study of H-β-zeolite supported Rh catalyst by inverse gas chromatography

“…Five grams of H-␤-zeolite (n(Si)/n(Al) = 12.5, Nankai University) was impregnated with appropriate volume of RhCl 3 ·3H 2 O (98%, Aldrich) solution (0.1 mol L −1 ) to prepare the catalyst containing Rh by the incipient wet impregnation method [36]. After drying under an infrared lamp, the catalysts were calcined at 573 K in air with a flow rate of 100 cm 3 min −1 for 30 min and then reduced at 773 K in H 2 with a flow rate of 20 cm 3 min −1 for 60 min.…”
