Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni3(HHTP)2 is proposed as an appealing 2D conductive MOF electrode material for energy-storage applications.
Caveat: Application performance is measured in a composite electrode/device; pristine material conductivity and porosity are not quantitatively reported.
1 and 8 · Abstract; 4. Summary · Linked to 4 structured results
The paper describes the MOF as porous but does not report BET surface area, pore volume, pore size or gas-sorption measurements in the supplied main article.
Caveat: Extraction is limited to the supplied main document; no SI was supplied.
1 and 5 · Abstract; 3.2. Electrochemical evaluation
PXRD and Raman features are presented as evidence for formation of Ni3(HHTP)2.
Caveat: No CIF, refinement or quantitative phase analysis is supplied in the provided documents; assignment is by comparison to reported studies.
2 · 3.1. Structural and morphological study · Figure 2a-b · Linked to 5 structured results
The low ESR and negligible charge-transfer resistance are attributed to the highly conductive conjugated Ni3(HHTP)2 structure.
Caveat: The paper does not report direct four-probe or two-probe bulk electrical conductivity; conductivity is inferred from EIS of composite electrodes.
4-5 · 3.2. Electrochemical evaluation in three cell measurements · Figure 4 · Linked to 2 structured results
The Ni3(HHTP)2//AC device combines capacitive and diffusive components, giving hybrid charge-storage behaviour.
Caveat: Dunn-model contribution percentages are visually estimated from the figure because no numerical table is provided.
