Chemical control of the characteristics of Mo-doped carbon xerogels by surfactant-mediated synthesis

Original language description

Carbon xerogels doped with Mo were prepared by a sol?gel modified method for the resorcinol (R) ? formaldehyde (F) polymerization (RF-gels). The use of surfactants (S) yields composites (RFS-gels), the S molecules are incorporated to the gel structure generating different metal anchoring sites. The interaction of molybdate ions View the MathML source with RF and RFS-gels was analysed. The View the MathML source adsorption is favoured by the attractive interactions with the RFS-gel containing a cationicsurfactant, and by the presence of oxygenated chemical groups introduced by the non-ionic surfactant. The smallest Mo-loading was obtained in RFS-gels containing anionic surfactant as a consequence of repulsive interactions. The adsorbed Mo-species influence on the curing of the polymeric gels, inducing a larger shrinkage and a lower microporosity of the carbon xerogels. The dispersion and chemical nature of Mo particles depend also on the Mo-gel interactions. Stronger attractive interac
