摘要

Abstract A family of hybrid mesoporous materials with high temperature stability was obtained by the suitable covalent combination of two types of siloxane precursors. Specifically, cubic T 8 polyhedral oligomeric (POSS) and aryl bridged silsesquioxane monomers (1, 4-bis (triethoxysilyl) benzene, BTEB) play the role of nanobuilders. An optimal molar ratio of the two precursors (5–25 mol% of total silicon content from the BTEB ...
