Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CuCo-HITP has superior alkaline OER/ORR bifunctional electrocatalytic performance relative to Cu3(HITP)2.
Caveat: Application data are measured on Nafion/glassy-carbon working electrodes rather than bulk powders.

CuCo-HITP also outperforms Cu3(HITP)2 for bifunctional OER/ORR activity and stability in neutral PBS.
Caveat: No full Zn-air battery device data are reported in the main article; the neutral PBS tests are motivated by Zn-air cathode relevance.

Although the paper calls the frameworks conductive MOFs and invokes conductivity, it does not report a direct electrical-transport measurement such as bulk conductivity, film conductivity, Seebeck coefficient or Hall mobility.
Caveat: EIS and electrocatalytic charge-transfer comparisons are reported, but these are not standalone electrical-transport measurements of the pristine MOF.
main p.7 · Conclusion
CuCo-HITP is a bimetallic 2D porous conductive MOF analogous to Cu3(HITP)2, with Co incorporated into the Cu3(HITP)2 framework.
Caveat: The exact empirical stoichiometry of CuCo-HITP is not reported; bimetal content is supported by EDS/XPS and initial 1:1 metal ratio.
main p.2 · Material characterization · Figs. 1-3 · Linked to 9 structured results
The performance improvement is attributed to Co incorporation and bimetallic synergy, giving larger electrochemical surface area, faster catalytic kinetics and improved charge-transfer efficiency.
Caveat: The paper does not report direct electrical conductivity or fitted Rct values; charge-transfer improvement is inferred qualitatively from EIS semicircles and electrochemical metrics.
