Al-MCM-41, also known as aluminum-modified MCM-41, belongs to the ExxonMobil M41S family of ordered mesoporous molecular sieves.
While its framework is consistent with pure-silica MCM-41 — featuring a hexagonally ordered mesoporous arrangement, ultrahigh surface area, and large pore volume — the introduction of aluminum atoms into the silica framework brings a key benefit: the formation of tunable Brønsted and Lewis acid sites.
This unique combination of mesoporous mass-transfer efficiency + controllable acidity + excellent thermal / hydrothermal stability makes Al-MCM-41 an indispensable material across catalytic science, organic transformations, environmental remediation, and energy materials.
CTAB molecules self-assemble into micellar templates
Silicon & aluminum precursors condense around the template to form the mesostructured framework
Calcination removes the organic template → open mesoporous channels
The result is a highly ordered hexagonal mesoporous network with tunable acidic active sites and a surface area of 850–900 m²/g.

The Si/Al ratio refers to the molar ratio between SiO₂ and Al₂O₃.
Lower Si/Al → more Al → stronger acidity
Higher Si/Al → less Al → weaker acidity but higher structural stability
