nano-filler co-nanoparticles embedded in a silica aerogel matrix

In present research, we synthesized cobalt-based silica nanocomposites (co-sio2) from cobalt nitrate [co(no3)2] and tetraethoxysilane (teos) precursors by using a simple sol-gel method followed by supercritical drying techniques. the physicochemical and textual properties of the as synthesized nano composites were thoroughly investigated. the results indicated that the co-sio2 aerogels demonstrated homogeneous dispersion cobalt nanoparticles within silica matrix with mesoporous morphology, large specific surface area (802 m2/g) and larger pore size (9 nm) with less volume shrinkage. the physicochemical properties of the cobalt based silica nanomaterial were characterized by xrd, sem, n2 adsorptiondesorption and ftir techniques. cobalt-based silica nanocomposites can be produced using teos-based precursor and supercritical drying techniques. the prepared (co-sio2) nanocatalyst due to its magnetic nature with higher surface area (802 m^2/g) can be utilized in many emerging fields such as catalysis, water desalination, water splitting, gas-sensing application and organic pollutant degradation
