Notes:
RF (Resorcinol-Formaldehyde) aerogels and carbon aerogels were prepared through thesol-gel method following the routes of polymerization, gelation, supercritical drying and pyrolysisprocesses. The influence of fabrication parameters on the textural structure of the samples, e.g.,specific surface area, pore size, and pore size distribution, etc., were systematically investigated. Witha decrease in the R/F molar ratio, or an increase in the catalyst content within a limited range, theporosity of the nanostructure materials increases. The optimal temperature of pyrolysis for RF aerogelwas investigated by TGA (Thermogravimetric Analysis)
