Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CuNC (MOF) air cathodes outperform commercial Pt/C cathodes in aluminium-air battery discharge voltage and reach a reported peak power density of 138 mW cm-2.
Caveat: The text contains a likely typo naming 'pH-pNSC sample'; context and Fig. 6 indicate CuNC (MOF).

The non-MOF CuNC nanoparticle/control recipe is internally inconsistent: one passage states copper nitrate and product CuNC (CuCl2), while a later passage states copper chloride and product CuNC NPs.
Caveat: This affects exact reproducibility of the nanoparticle comparator but not the target CuNC (MOF) route.
p002 and p005 / 15820 and 15823 · Experimental; Results and discussion
Pyrolysis and small-molecule release increase porosity, with CuNC (MOF) showing the highest BET area and pore volume among Cu-MOF, Cu/C, and CuNC (MOF).
Caveat: No uncertainty or repeat statistics reported for BET values.
p004 / 15822 · Results and discussion · Fig. 3b · Linked to 6 structured results
Cu-MOF precursor morphology and melamine-assisted pyrolysis create fibre-like porous Cu/N/C with conductive carbon networks and Cu-N active sites.
Caveat: Final material is MOF-derived carbon rather than an intact conductive MOF framework.

Cu-N structures and N dopants provide active sites for ORR, and CuNC (MOF) shows near-Pt/C ORR activity with mainly four-electron transfer.
Caveat: The paper partly invokes previously reported DFT; no new computational results are first-hand here.
p005 / 15823 · Results and discussion · Fig. 4 · Linked to 4 structured results
The one-dimensional fibre-like CuNC (MOF) structure improves electron transport relative to CuNC nanoparticles by reducing interparticle ohmic contacts.
Caveat: Four-probe sample geometry is not specified in the SI table.
