5-methylresorcinol and the technical mixture of oil-shale phenolic compounds were applied for carbon aerogel
preparation. Gels, which were prepared via base catalyzed polymerization were dried under supercritical conditions and
subsequent pyrolysis of obtained dry aerogels led to carbon aerogels. Activation of carbon aerogel with CO2 and H2O was
performed and porosity and the specific surface area of activated carbon aerogels were studied. Langmuir specific surface
areas of well over 2000 m2/g were achieved and microporosity of carbon aerogel samples was tuneable ranging from below
50% until over 85%. Impregnation with the complex [Pd(C4HF6O)2] was carried out in supercritical CO2 using H2 for
a quick reduction of Pd(II) to Pd(0). Eventually, highly porous material decorated with nanoparticles of black palladium
was obtained having a homogeneous metal distribution.
