A novel process is described for the preparation of a microporous crystalline solid, known as IZM-2 microporous solid or IZM-2 zeolite. This novel process consists of carrying out the synthesis of IZM-2 zeolite by conversion/transformation of a zeolite with structure type FAU in a fluorinated medium under hydrothermal conditions. In particular, said novel process consists of carrying out the synthesis of an IZM-2 zeolite in a fluorinated medium starting from a zeolite with structure type FAU used as the source of silicon and aluminium and a specific organic molecule or template comprising two quaternary ammonium functions, namely 1,6-bis(methylpiperidinium)hexane dihydroxide.

The invention provides methods and compositions for precursors and for the synthesis of zeolites. The invention makes use of intimately homogeneous precursors which avoid the formation of a difficult to work with gel stage in zeolite formation. This allows for the synthesis of zeolite in a much shorter period of time and with much lower amounts of structure directing agents.

A composite material comprises a macroporous silicate-based material at least partially substituted with at least one microporous zeolite, wherein the microporous zeolite is functionalised with either copper, iron or both copper and iron, and wherein the composite material is in the form of particles. The composite material can be obtained using a method comprising the steps of: (i) providing a mixture comprising a silicate-containing scaffold having a macroporous structure, an aluminium source and an organic template; (ii) hydrothermally treating the mixture to form a microporous zeolite-containing structure substantially retaining the macroporous structure of the silicate-containing scaffold; (iii) incorporating copper, iron or both copper and iron into the zeolite. The silicate-containing scaffold can be a diatomaceous earth.
