The 3d-cubic Pm (3) over barn SBA-1 mesoporous silica synthesized under highly acidic conditions using cetyltrimethylammonium bromide exhibited a distinct octadecahedron crystal shape in contrast to the material synthesized in the presence of cetyltriethylammonium bromide under less acidic conditions, which showed a highly isotropic morphology with fifty-four or more crystal faces.
