Abstract
Mesoporous aluminosilicates (MAs) with excellent hydrothermal stability have been a growing interest because of their potential application in face-centered cubic. The process of improving the P123 utilization efficiency and reducing the water consumption is an important issue for the synthesis and application of MAs. In this study, trace amounts of alcohol ether sulphate (AES) being the co-template were introduced into high P123 concentration to synthesize MAs. The water consumption is reduced 77.3%, and P123 utilization efficiency is increased 1.2 times in comparison to that of the conventional method. In high P123 concentration solution, micelle aggregates were formed without AES, resulting in the formation of less ordered MAs. However, well-dispersed micelles were formed in the presence of AES, which is beneficial for the subsequent assembling process. In addition, the micellar state corresponding to different AES contents and the influence on physicochemical properties of MAs were discussed.
