Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
NiCu-CAT/GCE shows stronger paracetamol electrocatalytic response than bare GCE, with NiCu-CAT redox peaks and enhanced PA electrochemical response.
Caveat: The comparison is electrochemical; no absolute conductivity of NiCu-CAT is measured.
main p.5 · Electrocatalytic Behavior of Paracetamol · Figure 4A · Linked to 4 structured results
NiCu-CAT/GCE provides a 5-190 uM paracetamol linear range, near-5 uM determination limit, 1.01% repeatability RSD, more than 95.8% retained response after storage, and tolerance to tested interferents.
Caveat: Application performance is electrochemical/sensing performance; no direct bulk conductivity value for NiCu-CAT is reported. SI table values are available from the rendered SI surrogate.
main p.7 · Conclusion · Figures 5-6 · Linked to 12 structured results
NiCu-CAT is assigned as a 2D mixed-metal catecholate MOF with a hexagonal/honeycomb pi-conjugated framework.
Caveat: The structure is simulated using a Ni-CAT CIF as model, and the exact Ni/Cu stoichiometric formula is not explicitly reported.
main p.3 · Results - Characterization · Figure 1B-C · Linked to 4 structured results
The authors attribute conductive behaviour in metal-catecholate MOFs to 2D charge delocalisation through HHTP ligands and metal nodes, with pi-stacking within MOF layers supporting high electrical conductivity, redox activity and catalytic activity.
Caveat: No direct electrical conductivity value, EIS fitting parameter, or charge-transfer resistance value is reported in the supplied documents.
main p.1 and p.2 · Abstract; Introduction · Linked to 2 structured results
The authors expect paracetamol to enter Ni/Cu-CAT channels because the reported paracetamol dimensions are smaller than the reported 13 Angstrom pore/channel size.
Caveat: This is based on structural/CPK size comparison rather than direct adsorption or diffusion measurements.
main p.7 · Analytical Performance Characteristics · Supplementary Figure 7 · Linked to 5 structured results
Paracetamol oxidation at NiCu-CAT/GCE is interpreted as adsorption-controlled and proceeds through a two-proton/two-electron process.
Caveat: The mechanism follows the authors' CV/Laviron analysis; no independent spectroelectrochemical verification is reported.
