Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Optimised NiFeZn MOF nanosheets show the best OER activity among the Fe, Ni, NiFe and NiFeZn MOFs, with 233 mV overpotential at 10 mA cm-2 and 37.8 mV dec-1 Tafel slope.
Caveat: Activity is electrochemical OER performance, not direct electronic conductivity.
4 · Results and discussion 3.2 · Fig. 4 · Linked to 5 structured results
Electrochemical activation partially dissolves Zn, forming Zn defects and porous nanosheets that are proposed to increase active sites and improve electron/mass transport.
Caveat: Mechanistic link is inferred from post-activation microscopy/EDS and electrochemical performance; no direct conductivity value is reported.
5 · Results and discussion 3.3 · Fig. 6 · Linked to 3 structured results
The solvothermal water/DMAC route is presented as universal for NiFeM (M = Zn, Mn, Cu, Pb, Cd) trimetallic MOF nanosheets.
Caveat: The experimental precursor list inconsistently includes Co but not Pb, while figures/results include Pb but not Co.
6 · Conclusions · Linked to 5 structured results
NiFeZn MOF is claimed to have lower charge-transfer resistance than Ni, Fe and NiFe MOFs based on smaller Nyquist semicircle diameter.
Caveat: Only qualitative Nyquist comparison is reported in text; no fitted Rct numeric value is provided.
