摘要
Oligomeric titanium(IV) cation ([Ti(OH)x(H2O) y]z+)-intercalated niobate was prepared through a stepwise ion-exchange route, in which n-decylamine was employed as a preswelling agent and titanium isopropoxide as titanium source. Titania-pillared layered niobic acid was then obtained by calcining oligomeric titanium(IV) cation-intercalated niobate at 450 °C in air. Characterization of this pillared material indicated that the material had a porous layered structure with an interlayer distance of 1.38 nm and a BET (Brunauer-Emmett-Teller) surface area of 34 m2 · g -1. The layered structure was still retained after the pillared material was heated at 550 °C.
