A facile strategy to synthesize mesoporous aluminosilicates with reduced particle size

摘要

We report a facile strategy for synthesis of hydrothermally stable mesoporous aluminosilicates (MAs) from zeolite Y precursors by adding small amount of Tween-20. By the addition of suitable amount of Tween-20, P123-Tween complex micelles formed due to the interaction between hydrophobic chain of Tween and PPO units of P123. The hydrophilicity of the complex micelles was enhanced due to the incorporation of PEO units of Tween. As a result of this, the micelles could be well dispersed and MAs with reduced particle size could be readily obtained. (C) 2017 Published by Elsevier B.V.
