Abstract

Organic/inorganic hybrid mesoporous silica MSU-x with phenyl is synthesized by the single-step co-condensation of phenyltriethoxysilane(PTMS) and tetraethoxysilane(TEOS) using fattyalcohol polyoxyethylene ether(A(EO)9) as the template under neutral conditions.The samples are characterized by FT-IR,SAXRD,SEM,TGA and N2 adsorption-desorption.The results show that the organic/inorganic hybrid material still preserves a three-dimensionalworm-likestructure.The Ph-MSU-x has strong hydrophobicity,high thermal stability,large specific surface area,pore volume and narrow pore size distribution.
