Preparation and Initial Applications in Catalysis [Elektronische Daten] [Sandra Martínez, Laura Martín, Elies Molins, Marcial Moreno-Mañas, Anna Roig, Adelina Vallribera] Summary.: We prepared organic gels and organic and carbon aerogels doped with europium through sol-gel processes. Eu-gels were prepared by sol-gel polymerization of the potassium salt of 2,4-dihydroxybenzoic acid with formaldehyde followed by ion-exchange with Eu(OTf)3. Eu-organic aerogels were obtained after CO2 supercritical drying of the gels and Eu-carbon aerogels were obtained by pyrolysing the organic aerogels. The Eu-gels containing 12% europium proved to be efficient as recoverable catalyst in Michael additions. Springer-Verlag, 2006 Keywords.
