Porous silicon dioxide nanopowder, also known as silica or silicon dioxide is a fine, white powder with a porous structure. It is composed of nanoscopic particles of silicon dioxide, 5-20 nm in size and has a high surface area due to its porous structure.
Application
Silicon dioxide finds applications in various fields, ranging from catalysis to composite synthesis. Some major studies are listed here:
- Pickering emulsion polymerization using a silicon dioxide nanoparticle stabilizer to form molecularly imprinted polymers for steroid recognition.
- Mesoporous silica is used as a catalyst support in the preparation of multiwalled carbon nanotubes (MWCNTs).
- It is used as a ring opening of tetrahydrofuran-dimethanol to 1,2,6-hexanetriol.
- It maybe used to prepare silica/brominated poly(phenylene oxide) nanocomposites membranes for CO2 seperations.
- The composite scaffold of chitosan/chondroitin sulfate/nano-SiO2 was fabricated by lyophilization.
- Nanocomposites preparation of silica, single-wall carbon nanotubes, and graphite nanoplatelets in an epoxy matrix have been reported.6
- Dielectric spectroscopy study of the polystyrene/nanosilica model system has been studied.
- PMMA SiO2 nanocomposites were reported to be synthesized.
