Co-ZSM-5 and Mn-ZSM-5 synthesised directly from aqueous fluoride gels
Abstract
Isomorphously substituted zeolite ZSM-5 is synthesised using an aqueous, slightly acidic, fluoride medium incorporating tetrahalometallate compounds of cobalt and manganese; final products were characterised using XRD, SEM, XRF, FTIR, TG–DTA, and evidence of metal incorporation into the zeolite framework is given.
