Synthesis of porous chromia-pillared tetratitanate

摘要

The first chromia-pillared tetratitanate is prepared by the reaction of the layered tetramethylammonium-intercalated tetratitanate with an aqueous chromium(III) acetate followed by calcination at 400 degrees C. The new porous material has a specific surface area as high as 94 m(2) g(-1) and an interlayer distance of 1.06 nm along with a moderately strong acidity. The layered nature of the pillared material may be retained above 600 degrees C. (C) 1998 Academic Press. [References: 14]
