Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CoPc-Cu MOF/GCE is a sensitive platform for NIF determination with a wide linear range, low LOD, reproducibility, stability, selectivity, and successful tablet analysis.
Caveat: Application is electrochemical sensing; no direct bulk conductivity or thermoelectric property is measured.
6 · Conclusions · Linked to 7 structured results
XRD, FTIR, SEM/TEM/EDS, and XPS support successful synthesis of CoPc-Cu MOF.
Caveat: No CIF or single-crystal structure is provided in the assigned documents.
3 · Characterization of CoPc and CoPc-Cu MOF · Figure 1 · Linked to 7 structured results
The larger effective surface area of CoPc-Cu MOF/GCE provides more reaction sites and improves NIF adsorption/sensing response.
Caveat: Surface area is electrochemical effective area, not BET porosity.
4 · Chronocoulometry studies · Figure 2D-E · Linked to 4 structured results
CoPc-Cu MOF/GCE has lower charge-transfer resistance than bare GCE and CoPc/GCE, indicating improved electronic transmission.
Caveat: Rct values are visually estimated from Figure 2C because the article reports only a qualitative comparison.
4 · Electrochemical impedance spectroscopy (EIS) · Figure 2C · Linked to 3 structured results
NIF oxidation at CoPc-Cu MOF/GCE is adsorption controlled because peak current increases linearly with scan rate.
4 · Effect of scan rate · Figure 2F · Linked to 1 structured result
The electrode reaction mechanism for NIF oxidation at CoPc-Cu MOF/GCE involves two electrons and two protons.
Caveat: Mechanism is inferred from electrochemical slopes and Laviron analysis, not direct product characterisation.
