“…B. aus Platin), um die katalytischen Eigenschaften des Metalls [14,15] auf die poröse Struktur des Aerogels zu übertragen. [1,16,17] Feinstrukturierte mesoporöse Anordnungen aus katalytisch aktiven Metallnanopartikeln wurden zudem durch den Einsatz von Templaten aus künstlichen Opalstrukturen [18] oder Pilzen [19] gewonnen. Es existieren vielfältige weitere Beispiele für Überstrukturen aus Metallnanopartikeln: mesoporöse Platin-KohlenstoffVerbundstoffe, [20] über Dithiole verknüpfte Gold-Nanopartikel, [21] kettenartige Nanostränge aus Palladium-Lipid-Nanokügelchen, [22] elektrokatalytisch aktive nanoporöse PlatinAggregate, [23] Schäume [24] sowie hochgeordnete zwei-und dreidimensionale Überkristalle.…”

Trägerfreie makroskopische Aerogele wurden aus Platin‐, Gold‐ und Silber‐ sowie aus gemischten Gold‐Silber‐ und Platin‐Silber‐Nanoteilchenlösungen hergestellt. Die Hydro‐ und Aerogele sind voluminöse poröse Netzwerke, die sich aus Partikeln oder Drähten mit wenigen Nanometern Dicke zusammensetzen. Diese neuartigen Strukturen verfügen über ein enormes Anwendungspotenzial in der Katalyse und Nanophotonik.

“…The use of carbon as a catalyst carrier is widely recognized [7,8]. To impregnate the carbon network with metal nanoparticles, several methods have been developed, most starting with the impregnation of an oxidized salt or metal complex followed by the reduction [9][10][11].…”

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 CO 2 and H 2 O was performed and porosity and the specific surface area of activated carbon aerogels were studied. Langmuir specific surface areas of well over 2000 m 2 /g were achieved and microporosity of carbon aerogel samples was tuneable ranging from below 50% until over 85%. Impregnation with the complex [Pd(C 4 HF 6 O) 2 ] was carried out in supercritical CO 2 using H 2 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.
