Synthesis of monolithic mesoporous silica with a regular structure (SBA-15) and macropores in neutral aqueous solution at room temperature

摘要

A monolithic biporous silica material of SBA-15 type has been synthesized by the sol-gel method in a neutral aqueous solution in the presence of glycerol without heating. Synthesis has been performed using P123 triblock copolymer and a novel silica precursor containing ethylene glycol residues.
