摘要

Hydrated titanium sol particles-intercalated layered niobate was prepared through the reaction between n-decylamine-intercalated niobate and hydrated product of tetrabutyl titanate. The titania-pillared layered niobic acid then obtained by calcining the titanium sol particles-intercalated niobate at 450°C in air. The resulting material has been characterized by means of XRD, IR, BET surface area and pore size distribution measurement techniques. The pillared sample was porous (mainly mesopores), with a high BET surface area of 131.3m²·g^-1 and an interlayer distance of 1.26nm at 450°C. Test of thermal stability revealed that the structure of the titania-pillared layered niobic acid was stable after this material calcined at 550°C for 2h in air.
