摘要

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 CO_2 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.
