“…For comparison, the sample obtained by the SDMBS/P123 composite template has the area of surface 777 m 2 ·g –1 and volume of pore 0.84 cm 3 ·g –1 . Moreover, after the severe hydrothermal deactivation, retaining ratio of area of surface and volume of pore for HMQW-2.0 are 30.5 and 53.6%, respectively, indicating the high hydrothermal stability of samples obtained in the present investigation …”

We have reported the synthesis of mesoporous aluminosilicates (MAs) with high hydrothermal stability via assembly of basic characteristic structure units of typical microporous zeolite Y. In spite of this, high consumption of organic template and H 2 O remains a major obstacle to its industrial application. Herein, a facile and effective strategy called "composite templates" was employed to decrease significantly the amount of P123 and H 2 O. In this method, composite micelles of P123/ poly(vinyl alcohol) (PVA) could be more easily dispersed in the solution due to the lowering of water's surface tension caused by the free hydroxyl groups of PVA. Moreover, the improved assembly ability of composite micelles in high concentration solution leads to the synthesis of hydrothermally stable MAs with 45% decrease of organic template P123 and 81% that of water amount. It was found that by the introduction of composite templates, the textural properties such as the surface area of materials, volume of pore, size of pore, and thickness were enlarged simultaneously. Meanwhile, this article presented an understanding into the assembly of composite micelles in the process of synthesis of MAs.
