SBA-15 is a kind of mesoporous molecular sieve, and its synthesis is another important chemical technology emerging in recent years. Its high hydrothermal stability advantages have opened up new research fields for catalysis, adsorption separation and advanced inorganic materials. With the deepening of the research on SBA15, this achievement is bound to have a new breakthrough in the field of chemical industry.

SBA-15 has a two-dimensional hexagonal through-hole structure with a P3mm space group. In the XRD diffraction pattern, the main peak is around 1°, which is (10) crystal face peak. The second strongest peaks are (11) and (20) respectively. Other peaks are weaker and less visible. In addition, silica on the SBA-15 skeleton is generally amorphous, and no obvious diffraction peak can be observed in wide-angle XRD diffraction. Nearby, is (10) crystal face peak. The second strongest peaks are (11) and (20) respectively. Other peaks are weaker and less visible.
