Preparation crystalline mesoporous titania at mild conditions with inorganic titanium precursors
In order to avoid the damage on mesostructure by the high temperature treatment,inorganic titanium species were used as the precursors for the preparation of mesoporous TiO2 of crystalline framework at mild conditions.The influences of the precursor,additive,reaction pH and temperature on phase and textural structures of the products were investigated.The samples were characterized by XRD,N2 adsorption/desorption,FT-IR and SEM.The results show that anatase mesoporous TiO2 with large surface area could be obtained without calcination with Ti(SO4)2 as precursor or TiCl4 when SO42- was added.And the template could be completely removed by Soxhlet extraction.
