Alumina with a fairly large surface area (415 m2g−1) and narrow pore size distribution (pore diameter ∼3 nm), containing octahedral and tetrahedral aluminum, prepared by long chain neutral amine as the surfactant, shows some evidence of textured structure. This material also contains disordered hexagonal structures, but use of partially hydrolyzed aluminum alkoxide with short chain amine templates, results in amorphous alumina with a surface area of 340m2g−1. Use of a polyethylene oxide as the surfactant, did not give the mesoporous structure in the absence of the template.

Mesoporous aluminosilicate spheres of 0.3–0.4 Μm diameter, with different Si/Al ratios, have been prepared by surfactant templating. Surface area of these materials is in the 510–970 m2 g-1 range and pore diameter in the 15–20 å range.
