METHOD FOR OBTAINING DOPED CARBON GELS, GELS THUS OBTAINED AND USE THEREOF AS CATALYSTS

摘要

The invention relates to a method for the synthesis of carbon gels doped superficially with metal nanoparticles, based on the formation of macromolecules comprising a phenolic compound, an aldehyde and at least one surfactant, performing steps in a particular order and under controlled experimental conditions that allow the porosity, the nanostructure and the surface chemistry of the support to be adjusted, thereby obtaining high surface metal dispersion with high sintering resistance. The invention also relates to the carbon gels (aerogels, xerogels and cryogels) obtained using this method and to the catalytic uses thereof.
