SiO Fibers by Centrifugal Spinning with Excellent Textural Properties and Water Adsorption Performance.

Facile and innovative route for large-scale synthesis of SiO fibers with excellent textural properties and HO adsorption performance is presented. At first, a three-dimensional network of SiO precursor fibers was produced from tailored spun solutions (without any toxic elements and surfactants) by centrifugal spinning, which is a very modern fiber-synthesis technique, with numerous advantages over electrospinning. Upon thermal annealing of the precursor fibers, mesoporous amorphous SiO fibers with an ultrahigh surface area of up to 824 m/g and pore size distribution in the range of 2-10 nm were produced. Owing to the high number of OH groups available on the surface, the produced SiO fibers showed significantly better performance in HO adsorption compared to that of the reference silicagel.
