Micro-mesoporous alumina-zirconia nanocrystals with controllable textural properties are prepared using triblock copolymer F127 as a template via one-pot vapor-induced pathway. The BET surface area and pore volume of the samples increase with rising aluminum content. When the Al/Zr molar ratio is 0.6, the sample exhibits highest surface area of 313 m²/g of which 118m²/g in the form of micropores after high temperature calcination. Moreover, the incorporation of Al species enhances the structural stability of zirconia in tetragonal phase.

易于合成具有定制织构的微介孔氧化铝-氧化锆纳米晶体

以三嵌段共聚物F127为模板，通过一锅法气相诱导法制备了具有可控织构性质的微孔氧化铝-氧化锆纳米晶体。样品的BET表面积和孔体积随铝含量的增加而增加。当Al / Zr摩尔比为0.6时，样品在高温煅烧后表现出最大表面积为313m ² / g，其中118m ² / g为微孔形式。而且，Al物种的掺入增强了四方相中的氧化锆的结构稳定性。
