Crystallization of as-Mesocellular Silica Foam into
Crystallization of as-mesocellular silica foam (as-MCF) into TS-1 zeolites by conventional hydrothermal and dense-gel routes is reported. The TS-1 synthesized through the dense-gel route (TS-1-d) showed higher meso-macroporosity (0.311 vs 0.233 cm3/g) smaller particle size (130 vs 305 nm) and enhanced external surface area (86 vs 31 m2/g) than that synthesized under conventional
