Resumo(s)
Hybrid magnetic carbon composites have been recently proposed as the next step
in the evolution of catalysts for catalytic wet peroxide oxidation (CWPO), with several
synergistic effects arising from the combination of the high catalytic activity of metal
species with the proven catalytic properties of carbon-based materials in CWPO [1].
Bearing this in mind, this work sought the development of novel magnetic carbon
xerogels, composed by interconnected carbon microspheres with iron (Fe) and/or
cobalt (Co) microparticles embedded in their structure. As inferred from the extensive
characterization performed, materials with distinctive properties were obtained upon
inclusion of different metal precursors during the sol-gel polymerization of resorcinol
and formaldehyde, followed by thermal annealing.
