Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The electrodeposited conductive MOF films can serve directly as self-supporting zinc-air battery air cathodes without polymeric binders or added conductive agents.
Caveat: Device contains carbon cloth substrate, waterproof membrane and Ni foam; framework film itself is the active catalyst layer.

The paper supports high conductivity indirectly through EIS charge-transfer/solution resistance trends and DFT density-of-states, but it does not report a direct four-probe electrical conductivity value for the films.
Caveat: No absolute electrical conductivity (S cm-1) measurement was found in the main or SI documents.
6-7 · 2.2 Catalytic Properties for the Oxygen Reduction Reaction · Figure S16, Table S4, Figure 3j · Linked to 5 structured results
XPS elemental analysis confirms that the three bimetallic films contain both Ni and Cu, with actual Ni/Cu ratios of 2.3/0.7, 2.1/0.9 and 1.6/1.4 for 3/1, 2/1 and 1/1 feed ratios, respectively.
Caveat: Compositions are surface-sensitive XPS atomic percentages rather than bulk elemental analysis.

An appropriate Cu content in Ni2.1Cu0.9(HITP)2 gives the best overall ORR metrics among the tested M3(HITP)2 films.
Caveat: Ni1.6Cu1.4(HITP)2 has the same reported onset potential but lower half-wave potential and higher Tafel slope.
6 · 2.2 Catalytic Properties for the Oxygen Reduction Reaction · Figure 3b,c · Linked to 5 structured results
Cathodic electrodeposition generates OH- near the working electrode, deprotonating the preformed metal-HITP complex and depositing M3(HITP)2 directly on carbon cloth.
Caveat: Mechanistic proposal supported by equations and process description, not isolated intermediates.
2 · 2.1 Material Design and Structural Characterization · Equations 1-3; Figure 1a
Cu2+ incorporation breaks the D4h symmetry of NiN4/CuN4 centres through unpaired 3d9 electrons and Jahn-Teller distortion, changing conductivity and ORR energetics.
Caveat: Conductivity is discussed through EIS and TDOS trends rather than a direct four-probe conductivity measurement.
