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 Cu3(HHTP)2 synthesis recipe is first-hand but contains likely unit/OCR anomalies for HHTP and NMP amounts, so parsed recipe fields should be treated cautiously.
Caveat: Raw recipe values are preserved exactly; no correction was imposed.
main p.2 · Synthesis of c-MOF (Cu3(HHTP)2) and slurry preparation
The Cu3(HHTP)2//AC device combines battery-grade redox behaviour from Cu3(HHTP)2 with capacitive surface adsorption from activated carbon, enabling simultaneous energy and power performance.
Caveat: Device performance is measured on composite electrodes containing conductive carbon and binder, not on binder-free pristine MOF alone.
main p.8 · Hybrid device assembly · Fig. 5 · Linked to 5 structured results
PXRD, Raman, FTIR, SEM/EDX and BET are used to support successful formation of a hexagonal two-dimensional Cu3(HHTP)2 conductive MOF.
Caveat: The main text reports five PXRD peak positions while listing six assigned phases; no CIF is provided in the assigned documents.
main p.4 · Results and discussion - Structural characterizations · Fig. 2 · Linked to 6 structured results
Low ESR and negligible charge-transfer semicircle are interpreted as evidence of easy ion access and satisfactory conductive properties for Cu3(HHTP)2 electrodes.
Caveat: ESR includes electrode, electrolyte and roughness contributions, so it is not an intrinsic electronic conductivity value.
main p.7 · Half-cell electrochemical characterization · Fig. 3f; Table 1 · Linked to 2 structured results
Dunn-model analysis indicates capacitive contribution increases with scan rate while diffusive/redox contribution decreases.
Caveat: Numerical contribution percentages were visually estimated from a low-resolution 3D bar plot; use the qualitative trend preferentially.
main p.8-9 · Hybrid device assembly · Fig. 9g · Linked to 5 structured results
Cu3(HHTP)2 behaves as a battery-like positive electrode in three-electrode testing, with redox peaks and b-values near 0.5.
Caveat: Evidence is electrochemical; no standalone electronic conductivity measurement is reported.
