Organic templates of as-synthesized siliceous,MCM-41 and SBA-15 can be effectively removed by oxidation treatment.The highly ordered mesostructures and surface properties of inorganic frameworks were retained after the template being removed.MCM-41 and SBA-15 obtained after oxidation treatment showed larger pores and richer silanol groups compared with those obtained by conventional calcinations at 550 ℃ in air.The removing ratios of templates of MCM-41 and SBA-15 were respectively 88% and 98%.
Anionic chiral template Ibuprofen and cotemplate 3-Aminopropyltriethoxysilane were employed to synthesize mesoporous silica with spiral morphology,and the sample was characterized by using XRD,FT-IR,SEM and TEM methods,conforming its hexagonal mesoporous structure and spiral morphology.
