Photocatalytic Reactions

Highly photoactive ZnO thin films have been prepared by sol-gel process on glass substrates. The influence of annealing temperatures on degradation rates has been studied, the inactivation and regeneration of photocatalytic properties of ZnO thin films have also been further discussed. The results show that the best annealing temperature is 300oC, surface active sites of new prepared thin films will be passive after the first photocatalytic reactions, photocatalytic performance successively reduced. H2O2 processed films can make the photocatalytic activity basically return to the level of new prepared films, can satisfy the need of repetitive use.

AbstractTitanium hexacyanoferrate microspheres (diameter <70km) were obtained in the following steps: (1) extraction of chlorides from an aqueous solution of TiCl4 with long chain amine -Primene JMT- in paraffin diluent (the resulting sol has the concentration 320 g TiO2/dm3 and the mole ratio Cl-: Ti4+ = 1.83); (2) blending of titania sol with an aqueous solution of K4 Fe(CN)6. 3H2O (280 g/dm3) in order to obtain final sols with Fe(CN)64-: Ti4+ mole ratio of 0.05 - 0.1; (3) formation of multicomponent sol emulsion in 2-ethylhexanol-1 containing I vol. % of Ethomen S/15 (EH), (4) gelation of emulsion drops by extraction of water with partially dehydrated EH; (5) filtration and washing with acetone; (6) drying at 140°C using a special procedure elaborated on the basis of TG and DTA studies.The final product is insoluble in water and exhibits high sorption efficiency of 137 Cs.
