Abstract
By controlling the pre-treatment of biomass materials and pyrolysis conditions, silica samples with various surface areas and levels of crystallinity were synthesized. With proper treatment, biogenic silica nanoaggregate (25-30 nm in diameter) can be synthesized from biomass materials. The characterizations revealed that the silica nanoaggregates were composed of smaller primary silica nanoparticles (ca. 4.2 nm in diameter). Under controlled melting catalyzed by metal salt cations, the silica nanoaggregates may be fuse to form semi-crystalline porous silica frameworks with tunable pore size and structural integrity. Organosilicon complexes were synthesized from the bio derived silica nanoaggregates.
