Abstract

Octa(dimethylsiloxy)silica cages (QM) undergo rapid self-polymerization in the presence of a fluoride catalyst to form complex 3D porous structural network materials with specific surface areas up to 650 m g. This establishes a new method to form bio-derived high inorganic content soft silicas with potential applications in filtration, carbon capture, catalysis, or hydrogen source.

摘要

八(二甲基硅氧)硅笼 (QM) 在氟化物催化剂存在下迅速自聚合，形成具有高达 650 m²/g 的比表面积的复杂三维多孔结构网络材料。这为形成具有潜在应用于过滤、碳捕获、催化或氢源的生物衍生高无机含量软硅石的新方法奠定了基础。
