These hierarchical TS-1 zeolites show an excellent catalytic behavior in olefin epoxidation reactions employing organic hydroperoxides as oxidants due to the presence of the secondary mesoporosity, which makes possible the access and interaction of bulky molecules with the Ti active sitesenAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Químicainfo:eu-repo/semantics/article10.1007/s11244-010-9590-9info:eu-repo/semantics/openAccess23 Química2391 Química Ambiental
