Abstract: 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 50 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.
