Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Pristine 2DCIF nanosheets can be used as efficient air-electrode catalysts in flooded and all-solid-state Zn-air batteries.
Caveat: Battery cathodes are composites on carbon supports with Nafion; performance is not solely a free-standing pristine framework property.
24596 · Conclusions · Fig. 4; Fig. S34 · Linked to 4 structured results
2DCIF is presented as a pristine, non-calcined Cu-based MOF electrocatalyst with notable ORR activity in alkaline media.
Caveat: ORR is electrochemical application performance, not direct electrical-conductivity measurement.
24591 · Introduction · Linked to 4 structured results
No direct electrical conductivity, Seebeck coefficient, carrier mobility, or thermoelectric transport value was reported for 2DCIF; conductivity is discussed only qualitatively in relation to nanosheet-enabled ORR mass/electron transport.
24590 · Abstract
2DCIF nanosheets show colloidal stability in methanol, water, and 0.1 M KOH for one month, and maintain morphology/structure during alkaline ORR testing.
Caveat: Acidic H2SO4 medium was reported unstable.
24594-24595 · Results and discussion · Fig. 3D; Fig. S19; Fig. S27-S31 · Linked to 5 structured results
The authors attribute ORR performance to uniformly distributed Cu-N4O active sites in a stable 2D framework with exposed Cu sites and ultrathin nanosheet morphology.
Caveat: Mechanistic link is inferred from structural/electrochemical correlation rather than operando proof of every intermediate.
24596 · Conclusions · Linked to 3 structured results
The synthesis/workup removes solvent sufficiently that no thermal activation or calcination is required for the pristine 2DCIF.
Caveat: No independent gas-accessibility activation comparison is reported beyond TGA/FTIR/porosity evidence.
14 · III.7 Thermogravimetric analysis · Fig. S15 · Linked to 3 structured results
Water, ICA linker, and suitable Cu(II) salts are necessary for nanosheet formation; MeImz, methanol solvent, and Cu(OAc)2 did not produce the desired MOF particles.
Caveat: Negative conditions are described by visual turbidity and SEM checks, not full quantitative yield tables.
