Applicable Classes

Name Description Modifies Slot
MechanochemicalSynthesis Catalyst preparation by mechanical milling or grinding, optionally
combined with thermal treatment.		 no
ElectrochemistryMixin Mixin providing electrochemical cell parameters shared by
electrochemical characterization techniques (CyclicVoltammetry,
ConductivityMeasurement).		 no
PowderXRD Powder X-ray diffraction for phase identification and structural analysis. 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
MolecularSynthesis Catalyst preparation by molecular (organometallic or coordination)
chemistry routes, including crystallisation and purification steps.		 no
RamanSpectroscopy Raman spectroscopy for vibrational and structural characterization. no
Solvothermal Catalyst preparation under elevated temperature and pressure in a
sealed vessel using a non-aqueous solvent.		 no
XPS X-ray photoelectron spectroscopy for surface elemental and chemical state analysis. no
CombustionSynthesis Catalyst preparation by combustion of a fuel/oxidizer mixture,
producing metal oxide catalysts in a single rapid step.		 no
Thermogravimetry Thermogravimetric analysis (TGA/DTG) for mass loss, decomposition, and oxidation state characterization. no
PlasmaAssisted Catalyst preparation using plasma treatment to modify surface
properties or deposit active components.		 no
InfraredSpectroscopy Infrared spectroscopy (FTIR/ATR) for functional group and surface species identification. no
Sublimation Catalyst preparation by sublimation: a solid precursor is vaporised
and deposited onto a substrate without passing through a liquid phase.		 no
DRIFTS Diffuse reflectance infrared Fourier transform spectroscopy for in-situ
surface species identification under reactive gas conditions.		 no
Reaction An EvaluatedActivity representing the catalytic reaction being studied.

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 carried_out_by as a ReactorDesignType (Device).
Reactants are linked via had_input_entity. The type of catalytic reaction
(e.g. ammonia synthesis, CO oxidation) is expressed via rdf_type using a
voc4cat or ChemO term.		 no
ConductivityMeasurement Electrical conductivity measurement for ionic and electronic transport characterization. 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
MicrowaveAssisted Catalyst preparation using microwave irradiation to rapidly and
uniformly heat the reaction mixture.		 no
CyclicVoltammetry Cyclic voltammetry for electrochemical activity, redox potential, and capacitance characterization. no
