Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni-Co-CAT cathodes gave the best COD removal among the tested MFC cathodes, attributed to faster cathode ORR kinetics and electron-transfer rate.
Caveat: COD removal is an MFC application metric, not an intrinsic framework conductivity measurement.

Ni-CAT and Ni-Co-CAT modified MFCs maintain stable maximum voltage longer than Pt/C during cycling, indicating good MFC application stability.
Caveat: Stability statement is qualitative from 30-day voltage curves; no quantitative degradation rate was reported.

The paper describes Ni-CAT and Ni-Co-CAT as conductive MOFs but does not report a direct electrical conductivity value for pristine powders or films.
Caveat: Electrical transport evidence is indirect, through electrochemical and MFC cathode behaviour.
748-755 · Abstract; 2.2; 4.5 · Figures 4-5
Introducing Co into Ni-CAT improves ORR activity and MFC power generation, as shown by higher limiting current density, higher maximum MFC voltage and higher power density for Ni-Co-CAT than Ni-CAT.
Caveat: Application cathodes are MOF/carbon black/PTFE composites, so MFC performance is not a direct pristine-framework transport measurement.

The authors attribute the better Ni-Co-CAT performance to higher porosity/surface area after mixing with carbon black and additional M-O6 (M = Ni or Co) active sites.
Caveat: Surface area is measured on MOF powders, while catalytic application uses MOF/carbon black/PTFE cathode composites.
