Carbon aerogels, cryogels and xerogels: Influence of the drying method on the textural properties of porous carbon materials
Nathalie Job,Alexandre Théry,René Pirard,José Marien,Laurent Kocon,Jean-Noël Rouzaud,François Béguin,Jean-Paul Pirard +7 more
TL;DR: In this article, the pore texture of both dry and pyrolyzed carbon gels depends on the drying process, and several more or less expensive methods (supercritical drying, freeze-drying, evaporative drying) were tested in order to determine which process is the most suitable for the synthesis of a porous carbon with a definite texture.
