| Abstract: | Oligomeric titanium(IV) cation (Ti(OH)x(H2O)y]&z?;)‐intercalated niobate was prepared through a stepwise ion‐exchange mute, 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 T. |
