SYNTHESIS AND PHOTO-DEGRADATION PROPERTIES OF C-DOPING MESOPOROUS TITANIUM DIOXIDE

Carbon-doping mesoporous titanium dioxide was prepared by evaporation-induced self-assembly method(EISA) with non-ionic surfactant P123 as structure directing agent,tetrabutyl titanate as titanium source and phenolic resin as additive.Succedently,mesoporous titanium dioxide could be obtained by calcining C-doping mesoporous titanium dioxide in ambient air.The prepared samples were characterized via XRD,SEM,TEM and N2 adsorption-desorption isotherms.The results indicated that C-doping titanium dioxide with worm-like mesoporous structure could be acquired by adding phenolic resin as additive and carbon source.The analysis on the adsorption and photo-degradation of dye-methyl violet revealed that C-doping mesoporous titanium dioxides possessed excellent adsorption properties while mesoporus TiO2 showed good adsorption and photo-degradation properties.
