A mesoporous(d=2.3mm)silica-pillared layered tetratita nate with a super gallery(d 001 =1.84mm)was prepared by first preswelling layered tetratitanate with n-dodecyl amine,then reacting with 20wt%NH 2 (CH 2 ) 3 Si (OC 2 H 5 ) 3 aqueous solution,and finally calcinating the resultant solid product i n air at 550℃.All the reaction was carried out hydrothermally in an aut oclave at 130℃.The obtained materia l has a relatively high BET surface area of204m 2 ·g -1 and a thermal stability beyond 600℃.The catalytic application of the material was also investigated by using the dehydration of isopropanol and the reform of n-hexane as two probing reactions.

All the reaction was carried out hydrothermally in an autoclave at 130 ° C. The obtained materia l has a relatively high BET surface area of 20 4 m 2 · g -1 and a thermal stability beyond 600 ° C. The catalytic application of the material was also investigated by using the dehydration of isopropanol and the reform of n-hexane as two probing reactions.
