Abstract

One aspect is a production process including feeding a feed material composition into a reaction zone at a feeding position, wherein the feed material composition is liquid or gaseous or both; reacting the feed material composition in the reaction zone into a first plurality of particles by a chemical reaction; depositing the first plurality of particles onto a substrate surface of a substrate, thereby obtaining a porous silicon dioxide material, having a pore structure, in the form of up to 20 layers superimposing the substrate surface; at least partially removing the porous silicon dioxide material from the substrate surface; and modifying the pore structure of the porous silicon dioxide material, thereby obtaining the porous silicon dioxide material having a further pore structure.
