Abstract

Taking TiCl

FeCl

·6H

O and NH

·H

O as the raw materials

surfactant CTAB as the templet and structure-directing agent

nano-TiO

mesoporous materials doped with Fe were synthesized by hydrothermal method. The as-synthesized titania was characterized by XRD

TEM and N

adsorption-desorption isotherm. It is found that the particles get primarily spherical and well dispersed with anatase phase

the crystallite size is approximately within the range of 10-15 nm

and the pore structure among particles appears as mesoporous texture lacking long-range order with the most probable aperture about 20 nm. Compar

ed with ordinary nano-sized powder

the mesoporous materials are endowed with much higher adsorption capability and decolorization rate for dye. Being irradiated under the sunlight for 60 min

the compound completely degrades the blue dye.
