Fluoride-Induced Hierarchical Ordering of Mesoporous Silica in Aqueous Acid-Syntheses

Hierarchical ordering of mesoporous silica induced by fluoride addition is described for aqueous acid‐syntheses. The authors report that small amounts of fluoride make it possible to control the organization of the mesoporous materials on different length scales. At low pH, fluoride addition brings...

Summary:Hierarchical ordering of mesoporous silica induced by fluoride addition is described for aqueous acid‐syntheses. The authors report that small amounts of fluoride make it possible to control the organization of the mesoporous materials on different length scales. At low pH, fluoride addition brings about the formation of large hydrothermally stable silica rods (see Figure) consisting of aligned bundles of mesoporous silica fibers.
