Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CoCu-MOF delivers the highest reported capacitance among the three studied MOF electrodes, 618 F g-1 at 1 A g-1, exceeding Co-MOF by more than two times and Cu-MOF by four times.
Caveat: Co-MOF and Cu-MOF 1 A g-1 values were not tabulated and are approximate figure-axis reads.

CoCu-MOF retains 75% capacitance after 3000 cycles, and the authors explicitly note cycling stability needs further improvement.
5 · Results and Discussion · Figure 5h · Linked to 1 structured result
The rendered SI Table S1 lists columns headed Cu+ and Cu2+ with values opposite to the main-text interpretation; extracted oxidation-state fractions follow the main text, abstract and conclusion.
Caveat: Manual review recommended before using SI Table S1 as a standalone source.
4 · Supporting Information · Table S1 · Linked to 4 structured results
CoCu-MOF forms a new crystal structure distinct from Cu-MOF and Co-MOF and is most likely an aggregation of 2D nanosheets.
Caveat: No CIF or full structural model is reported; assignment is based on XRD peak differences and morphology.
3 · Results and Discussion · Figure 2b · Linked to 3 structured results
The enhanced electrochemical performance of CoCu-MOF is attributed to larger surface area than Co-MOF, Cu+-related redox sites and lower impedance/faster charge transport.
Caveat: Direct electronic conductivity was not reported; electrical-transport evidence is inferred from EIS/ESR in composite electrodes.
6 · Results and Discussion / Conclusion · Linked to 6 structured results
Cu incorporation in CoCu-MOF introduces a high Cu+ fraction and dual Co/Cu redox sites, increasing active sites for supercapacitor reactions.
Caveat: Cu+/Cu2+ fractions are taken from the main-text interpretation; SI Table S1 has an apparent header inconsistency.
