Towards the Loewenstein limit (Si/Al=1) in thermally stable mesoporous aluminosilicates
Abstract
The use of complexing agents to generate polynuclear precursor species containing both Al and Si allows the synthesis of thermally stable mesoporous aluminosilicates including solely tetrahedrally coordinated aluminium, in which the Si/Al ratio can be modulated down to a minimum Si/Al value of 1.06(4).
