Beschreibung
Zusammenfassung:	A mesoporous titanium phosphate with high surface area was synthesized in an alcoholic system containing a small quantity of water using n-octodecylamine as structure-directing agent. The stability and structure order of the product treated by post-synthetic treatment can be improved remarkably after removal of the structure-directing agent by acidified ethanol extraction. The mesoporous product calcinated at 500 °C exhibits wormhole-like pore structure and high surface area about 497 m2/g.
