Applicable Classes

Name	Description	Modifies Slot
PowderXRD	Powder X-ray diffraction for phase identification and structural analysis.	no
InfraredSpectroscopy	Infrared spectroscopy (FTIR/ATR) for functional group and surface species identification.	no
DRIFTS	Diffuse reflectance infrared Fourier transform spectroscopy for in-situ surface species identification under reactive gas conditions.	no
NMRSpectroscopy	Nuclear magnetic resonance spectroscopy for structure elucidation. Note: for detailed liquid-state NMR minimum information, the dedicated nmr_dcat_ap profile (MARGARITAS) should be used in combination with this subprofile.	no
Sublimation	Catalyst preparation by sublimation: a solid precursor is vaporised and deposited onto a substrate without passing through a liquid phase.	no
ThermalSynthesisMixin	Mixin providing thermal process parameters common to synthesis methods carried out at elevated temperature in a closed vessel or reactor (Solvothermal, PlasmaAssisted, CombustionSynthesis, MicrowaveAssisted, MechanochemicalSynthesis, Sublimation).	no
MolecularSynthesis	Catalyst preparation by molecular (organometallic or coordination) chemistry routes, including crystallisation and purification steps.	no
CombustionSynthesis	Catalyst preparation by combustion of a fuel/oxidizer mixture, producing metal oxide catalysts in a single rapid step.	no
MechanochemicalSynthesis	Catalyst preparation by mechanical milling or grinding, optionally combined with thermal treatment.	no
CyclicVoltammetry	Cyclic voltammetry for electrochemical activity, redox potential, and capacitance characterization.	no
PlasmaAssisted	Catalyst preparation using plasma treatment to modify surface properties or deposit active components.	no
Thermogravimetry	Thermogravimetric analysis (TGA/DTG) for mass loss, decomposition, and oxidation state characterization.	no
ElectrochemistryMixin	Mixin providing electrochemical cell parameters shared by electrochemical characterization techniques (CyclicVoltammetry, ConductivityMeasurement).	no
ConductivityMeasurement	Electrical conductivity measurement for ionic and electronic transport characterization.	no
Solvothermal	Catalyst preparation under elevated temperature and pressure in a sealed vessel using a non-aqueous solvent.	no
CatalyticReaction	A ChemicalReaction (chemdcat-ap) specialization representing the catalytic reaction being studied. Inherits the generic reaction slots (starting materials, reactants, products, catalyst, solvent, reactor, temperature, pressure, yield, reaction steps) from ChemicalReaction and adds catalysis-specific operating-condition slots. Reaction is NOT a DataGeneratingActivity — it is the catalytic process being observed, not the process that generates the dataset. A CatalysisDataset is linked to the Reaction it is about via is_about_activity. For operando experiments (e.g. in-situ XRD during a reaction), the dataset carries both: was_generated_by: Characterization (the measurement producing data) is_about_activity: Reaction (the catalytic process being monitored) The reactor is linked via the inherited used_reactor slot (is_a: carried_out_by), narrowed here to require a ChemicalReactor instance rather than touching the generic carried_out_by relation directly. Reactants are linked via the inherited used_reactant slot (range: Reagent) -- CatalyticReaction does not declare its own reactant slot. The type of catalytic reaction (e.g. ammonia synthesis, CO oxidation) is expressed via rdf_type using a voc4cat or ChemO term.	no
XPS	X-ray photoelectron spectroscopy for surface elemental and chemical state analysis.	no
RamanSpectroscopy	Raman spectroscopy for vibrational and structural characterization.	no
MicrowaveAssisted	Catalyst preparation using microwave irradiation to rapidly and uniformly heat the reaction mixture.	no
