A system of terms and rules for writing standardized crystal chemical formulas for ordered microporous and mesoporous materials is proposed by L. B. Mccusker of ETH Zurich. The nomenclature encompasses all inorganic materials with ordered, accessible pores with free diameters of less than 50 nm. The crystal chemical formula describes the composition of guest and host species, host structure, pore system structure, and material symmetry.
Use Cases
- Standardizing material descriptions based on the proposed nomenclature system.
- Classifying ordered porous materials based on pore diameter and inorganic host structure.
- Generating simplified or expanded crystal chemical formulas for specific reporting requirements.
- Facilitating consistent communication in research publications on microporous and mesoporous materials.
Strengths
- Provides a systematic classification scheme for a defined class of materials (pores < 50 nm).
- Crystal chemical formula is designed to be adaptable, allowing simplification or expansion.
- Based on recommendations from both common usage and systematic principles.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
