文摘
Highly ordered mesoporous zirconium oxophosphates (designated as ZOP) with hexagonal P63/mmc and cubic 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 , hexagonal P63/mmc and cubic . The ZOP mesoporous materials with cubic and hexagonal P63/mmc structures were stable up to 800 °C, which provides a new insight into the structural factors governing self-assembly of thermally stable mesoporous materials and would open up new possibilities of porous materials for advanced applications.
