Abstract:

A silica-pillared layered ferrititanate was successfully prepared by first preswelling K(0.8)Fe(0.8)Ti(1.2)O4 with n-hexylammonium chloride, and then reacting with NH2CH2CH2CH2Si(OC2H5)3 and finally calcinating the resultant product in air at 500℃ .The obtained silica-pillared layered ferrititanate has a high thermal stability beyond 650℃ and a specific surface area of 98.0m2•g(-1).

Key words: Layered ferrititanate, Silica pillar, Preparation
