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.
The optimised 0.05 mL/mg PdCl2-loaded Pd(II)@Ni3(HITP)2 sample gives ultrasensitive CAP detection with 0.2 nM LOD and 0.0002-20 μM linear range.
Caveat: Sensor performance is application-specific rather than intrinsic transport performance.
9 · Conclusion · Linked to 5 structured results
Although current responds promptly to CAP addition in CA monitoring, the response decays, limiting real-time use to qualitative analysis.
Caveat: No quantitative CA calibration extracted from Figure S12.
8 · pH Resistance, Anti-Interference and Real Sample Test · Figure S12 · Linked to 1 structured result
Ni3(HITP)2 serves as a conductive porous support/carrier that captures CAP, disperses PdCl2, and improves stability/sensitivity relative to PdCl2 alone.
Caveat: Direct CAP adsorption configuration is cited to previous research, not newly computed in this paper.
6-7 · Electrocatalytic Detection of CAP · Linked to 5 structured results
PdCl2 loading leaves the Ni3(HITP)2 framework morphology/characteristic FTIR peaks largely unchanged while introducing PdCl2 features.
Caveat: XRD indicates changes including shifted/vanishing features, so the claim is framed as largely retained morphology/characteristic peaks.
2-4 · Characterization and Loading Mechanism · Figures 1, 3, 4 · Linked to 4 structured results
Pd loading in Pd(II)@Ni3(HITP)2 is dominated by PdCl2 adsorption on abundant N, Ni, and benzene sites rather than Pd substitution for Ni.
Caveat: DFT sign convention noted because text reports adsorption magnitudes while figure plots favourable negative energies.
