Here, combining the evaporation-induced self-assembly (EISA) method and the liquid crystal templating pathway, mesostructured amorphous zirconium oxides have been prepared by a soft templating method without addition of any heteroelement to stabilize the mesopore framework. The recovered materials have been characterized by SAXS measurements, nitrogen adsorption–desorption analysis and X-ray diffraction (XRD). The obtained mesostructured zirconia exhibits a high thermal stability. An in situ XRD study performed as a function of temperature shows that the amorphous ZrO₂, obtained after removal of the pore templating agent (pluronic P123), begins to crystallize in air from 420 °C. Amorphous mesostructured ZrO₂ also presents a high hydrothermal stability; these materials are not degraded after 72 hours in boiling water.

具有高（水）热稳定性的非晶介孔氧化锆

在这里，结合蒸发诱导自组装（EISA）方法和液晶模板途径，通过软模板方法制备了介孔结构的非晶氧化锆，无需添加任何异质元素来稳定介孔骨架。回收的材料已通过 SAXS 测量、氮吸附-解吸分析和 X 射线衍射 (XRD) 进行了表征。获得的介孔结构氧化锆表现出高的热稳定性。作为温度函数进行的原位XRD 研究表明，在去除孔模板剂 (pluronic P123) 后获得的无定形 ZrO ₂从 420 °C 开始在空气中结晶。非晶介孔结构 ZrO ₂还具有很高的水热稳定性；这些材料在沸水中 72 小时后不会降解。
