Synthesis of mesoporous ordered silica with structure of MCM-41

Mesoporous ordered silica with structure of MCM-41were prepared by template synthesis using sodium silicates as precursor of silica. It was shown that prepared materials had specific surface area above 1000 m2/g and pore volume of 0,84‒1,14 cm3/g. The structure of MCM-41 formed by self-assembly of silica molecules with surfactant molecules (CTAB) possessed a hexagonal arrangement of uniformly sized mesopores of 2,5‒4,0 or 3-5 nm. Thus, template synthesis allows creating stable silica with specified porous structure, which may be used as support for heterogeneous catalysts and functional nanomaterials
