A process of manufacturing inorganic nanofibers, without using an organic polymer, using a highly reactive metal alkoxide such as titanium alkoxide or zirconium alkoxide, in particular, a process in which inorganic nanofibers can be stably produced over a long period, is provided. It is a process of manufacturing inorganic nanofibers by electrospinning using a sol solution containing an inorganic component as a main component, characterized in that the sol solution contains a metal alkoxide having a high reactivity and a salt catalyst, and that the salt catalyst is an amine compound having an N—N bond, an N—O bond, an N—C═N bond, or an N—C═S bond.
A process of manufacturing inorganic nanofibers by electrospinning using a sol solution containing an inorganic component as a main component, characterized in that the sol solution contains a metal alkoxide having a high reactivity and a salt catalyst, and that the salt catalyst is an amine compound having an N—N bond, an N—O bond, an N—C═N bond, or an N—C═S bond.
Inorganic nanofibers prepared by forming inorganic gel fine fibers by electrospinning using a sol solution containing an inorganic component as a main component, and heat-treating the inorganic gel fine fibers to obtain the inorganic nanofibers, wherein said sol solution contains a metal alkoxide having a high reactivity and a salt catalyst, the salt catalyst is an amine compound having an N—N bond, an N—O bond, an N—C═N bond, or an N—C═S bond, and an unreacted alkoxy group of the metal alkoxide remains.
Inorganic nanofibers having micropores prepared by forming inorganic gel fine fibers by electrospinning using a sol solution containing an inorganic component as a main component, and heat-treating the inorganic gel fine fibers to obtain the inorganic nanofibers, wherein said sol solution contains a metal alkoxide having a high reactivity and a salt catalyst, and the salt catalyst is an amine compound having an N—N bond, an N—O bond, an N—C═N bond, or an N—C═S bond.
