These materials display good catalytic activity in the epoxidation of olefins with alkyl hydroperoxides, being the catalytic activity correlated with the nature of supported molybdenum species. The immobilized metal species show different stabilities against leaching depending on their nature. Reutilization catalytic tests indicate that some fraction of the molybdenum show a high stability and it seems to be responsible for the major part of the catalytic activity of these materials. Stable molybdenum species use in a very efficient manner the alkyl hydroperoxide in the epoxidation of olefins whereas leached species leads to non-oxidative consumption of the oxidant and promote secondary reactions.enAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Materialesinfo:eu-repo/semantics/article10.1016/j.apcata.2007.07.031info:eu-repo/semantics/openAccess2391 Química Ambiental
