Enum: CatalysisResearchFieldEnum

Enumeration of catalysis research fields.

Intended for use via rdf_type on a dcat:Dataset (via ClassifierMixin)

to classify which field of catalysis the dataset belongs to,

following DCAT-AP-PLUS Pattern 3 (Flexible classification).

URI: coremeta4cat:enum/CatalysisResearchFieldEnum

Permissible Values

Value Meaning Description
heterogeneous_catalysis VOC4CAT:0007001 Heterogeneous catalysis — catalyst and reactants are in different phases.
homogeneous_catalysis VOC4CAT:0000294 Homogeneous catalysis — catalyst and reactants are in the same phase.
biocatalysis VOC4CAT:0000204 Biocatalysis — use of enzymes or whole cells as catalysts.
electrocatalysis VOC4CAT:0000216 Electrocatalysis — catalysis of electrochemical reactions.
photocatalysis VOC4CAT:0000001 Photocatalysis — catalysis of a chemical reaction through the
absorption of sufficient light energy by a photocatalyst.
hybrid_catalysis None Hybrid catalysis — combination of two or more catalytic approaches.
other None Other catalysis research field not covered by the above terms.

Name Description
catalyst_type The catalytic regime of the reaction (e.g. heterogeneous, homogeneous,
biocatalysis, electrocatalysis, photocatalysis). For the physical
form/presentation of the catalyst itself, use catalyst_form instead.

Deliberately kept recommended rather than required (see nfdi4cat/
CoreMeta4Cat#117): classification here can be genuinely disputed or
not yet covered by CatalysisResearchFieldEnum for a novel catalyst,
and forcing a value would push researchers into a premature or
contested classification rather than leaving the field unset until
consensus/vocabulary catches up. Open for discussion in a follow-up
issue if a different tradeoff is wanted. See also nfdi4cat/
CoreMeta4Cat#116 on whether this two-slot design (catalyst_type +
catalyst_form) or PR #118's CatalystType class hierarchy should be
the long-term mechanism -- kept as two enums here because the
VOC4CAT terms show CatalystType conflates the regime axis
(Heterogeneous/Homogeneous/Bio/Electro/Photo) with the physical-form
axis (ThinFilm/Bulk/Powdered/DepositedSample/Supported -- identical
VOC4CAT ids to catalyst_form's permissible values), which are
independent and often both apply to the same catalyst at once.
