SBA-3 is a quaternary ammonium salt as template acid synthesis in mesoporous silicon-based system has a two-dimensional hexagonal structure of zeolite. Mesoporous material of the synthetic material and the alkaline system is different, the difference in its backbone is neutral or near neutral silica, rather than a negatively charged silicate.
