Carbon aerogels are highly porous materials with a large specific surface area, usually made from porous supercritically dried organic aerogels pyrolysing these at high temperatures.
For example, Pekala was the first to obtain organic aerogels by supercritically drying gels, which were made through sol-gel polymerization by using resorcinol (R) and formaldehyde (FA) as precursors [1, 2].
