Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
C2-ZIF-67 is the best-performing sample in this study for supercapacitor capacitance, energy density, and cycling stability.
Caveat: Performance is measured in a three-electrode aqueous KOH configuration; device-level full-cell data are not reported.

Co-MOF (ZIF-67) controls the morphology and porous structure of pre-hydrolysate-based carbon materials.
Caveat: Claim is based on comparative morphology/porosity of carbon-hydrolysate, Co-MOF, C1-ZIF-67 and C2-ZIF-67; no independent mechanistic kinetics are reported.
p011-p012 / article pp.11-12 · 4 Conclusions · Linked to 4 structured results
Hierarchical pores, especially pores in the 2.0-5.0 nm range, are claimed to provide channels for ion transport, active sites, and electrolyte storage/rapid transfer.
Caveat: The 2.0-5.0 nm range is discussed as beneficial; Table 1 average pore sizes are 8.4 and 11.9 nm.

The hollow dandelion-like C2-ZIF-67 structure is proposed to shorten electron/charge transport paths and promote charge and mass transfer.
Caveat: No direct electronic conductivity value is reported; EIS trends are qualitative.
p007-p011 / article pp.7-11 · 3 Results and Discussion · Figure 8a · Linked to 4 structured results
The authors claim small amounts of Co-MOF active/free electrons can be stored and released through redox reactions, improving electrical conductivity of Carbon-ZIF-67 materials.
Caveat: The paper does not report a direct conductivity measurement; this is an inferred mechanism supported by XPS, CV and EIS trends.
