Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Loading MIL-53(Fe) on SS as the cathode substantially improves MFC power generation, with maximum power density of 397 +/- 6.3 mW/m2, 73.5 times the bare electrode.
Caveat: Application comparison is against bare SS only; no Pt/C benchmark experiment is reported in this paper.
6 · 3.3; 4. Conclusions · Fig. 5 · Linked to 4 structured results
The MIL-53(Fe)/SS cathode shows stable MFC voltage output around 0.37 V for one week and no maximum-voltage decrease over one month, indicating operational durability.
Caveat: Voltage cycling is reported graphically and in narrative text; no replicate statistics for long-term voltage are reported.
6 · 3.3 · Fig. 5d · Linked to 4 structured results
Although the article states that MIL-53(Fe)/SS had good electrical conductivity and charge-transfer behaviour, it reports no standalone electrical-transport measurement or conductivity value for pristine MIL-53(Fe).
Caveat: Conductivity evidence is indirect through ORR currents and MFC output.
2,6 · Introduction; 3.3 · Fig. 4; Fig. 5 · Linked to 3 structured results
The prepared powder was assigned as high-purity MIL-53(Fe) based on XRD peaks at 9.0, 12.3 and 25.2 deg 2theta and FTIR bands associated with carboxylate, Fe-O and linker vibrations.
Caveat: No CIF or Rietveld refinement details are provided in the assigned documents.
4 · 3.1 · Fig. 2 · Linked to 5 structured results
MIL-53(Fe)'s porous, blocky three-dimensional structure, rich voids and large surface area are proposed to provide more electrochemically active sites and improve ORR catalytic performance.
Caveat: Porosity is not quantified by BET or pore-size analysis in the main article.
1,4-6 · Abstract; 3.1; 3.3 · Fig. 3; Fig. 5 · Linked to 4 structured results
The Fe redox process in MIL-53(Fe) is claimed to store electrons and provide a path for electron transfer, improving ORR behaviour.
Caveat: No intrinsic electronic conductivity value or charge-transfer resistance is reported.
