Abstract

A three-stage temperature-programmed (TP) calcination route to remove the templates from hexagonal mesoporous aluminophosphates (meso-AlPO) was developed. XRD results showed that the condensation and order degrees of inorganic framework of meso-AlPO calcined by this TP route were greatly increased, which is much better than the conventional method. It was also found that the shrinkage of the pore structure decreased and further the pore size of the product became larger than the previous report. This shows a novel calcination route to improve highly ordered mesostructures and the thermal stability of the meso-AlPO materials. © 2006.
