Structure and thermal stability of mesostructured zirconium oxophosphates

Highly ordered mesoporous zirconium oxophosphates (designated as ZOP) with hexagonal P63/mmc   and cubic Fm3¯m symmetries were firstly prepared by using gemini cationic surfactants as templates. It has been found that the thermal stability was elevated with the structure curvature order: cubic Ia3¯d<2D-hexagonalp6mm
