The typical inner structure is composed of nanotubes having diameters around 3.5 nm aligned along the radius of the spherical particles, with surface areas around 1,000 m2/g, depending on the surfactant (C16H33N(CH3)3 Br) to co-solvent (CnH2nnull1OH, where nnull2,3, or CH3COCH3) molar ratio. Elliptical particles are also obtained with cylindrical pores running along or across the major axis of the particles having very high surface areas of up to 1561 m2/g and a mean pore diameter of 2.0 to 4.0 nm. The walls of the nanotubes are pure silica or a composition of silica with M(III)Ox where M is a trivalent metal such as Al, Ga, or lanthanide.
