Preparation of Nano-ZnFe2O4 Doped TiO2 Photocatlytic Films on Porous Hayddites
Applied nano-ZnFe2O4/TiO2 photocatlytic films were prepared by template sol-gel method on porous haydites.The effects of ZnFe2O4-doping on TiO2 crystallization,sintering temperature,light absorption and photocatalysis were mainly studied,simultaneously,effect of template,amphiphilic block copolymer P(styrene-b-acrylic acid) (PS-b-PAA) on the phtocatalytic activity of ZnFe2O4/TiO2 films are also studied.The results showed that right amount of ZnFe2O4-doping reduced TiO2 sintering temperature and particle size,and increased TiO2 absorbency in ultraviolet region,and a right amount of template (PS-b-PAA) formed orient arranged ZnFe2O4/TiO2 films with the high photocatalytic activity and decomposed fully methyl orange in water after light irradiating 2h.
