Nomenclature of Structural and
Compositional Characteristics of Ordered Microporous and Mesoporous
Materials with Inorganic Hosts
A system of terms
applicable to ordered microporous and mesoporous materials is proposed,
and rules for writing a standardized crystal chemical formula for such
materials are presented. The recommendations are based both on common
usage and on a systematic classification scheme. The nomenclature has
been developed to encompass all inorganic materials with ordered, accessible
pores with free diameters of less than 100 nm. The crystal chemical
formula describes the chemical composition of both the guest species
and the host, the structure of the host, the structure of the pore system,
and the symmetry of the material. This formula can be simplified or
expanded to suit the user's requirements.
