Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The trimetallic NiCoFe-CAT electrode is the best BA oxidation catalyst among the paper's M-CAT series, with the lowest potentials at i10/i50/i100 and high BN yield/FE.
Caveat: Electrochemical sample is a composite electrode containing acetylene black, PVDF, and carbon cloth; values are not pristine powder transport metrics.
7 · Conclusions · Linked to 5 structured results
NiCoFe-CAT retains BA oxidation activity over cycling, but activity decreases to about 66% after five cycles, possibly from partial framework collapse in stronger alkaline/quintuple BA conditions.
Caveat: Framework collapse is presented as a possible explanation; morphology after 10 h still maintains nanowires, so degradation is not fully resolved.
7 · Results and Discussion · Figure 4i · Linked to 2 structured results
Co and Fe incorporation preserves the Ni-CAT framework and yields isostructural multimetal M-CAT nanowires.
Caveat: PXRD/text establish phase similarity; no CIF for the new mixed-metal samples was provided in the assigned files.
4 · Results and Discussion · Figure 2 · Linked to 5 structured results
The 2D layered M-CAT structure with approximately 2 nm 1D channels is proposed to provide a reaction platform for benzylamine oxidation.
Caveat: The channel argument is structural/interpretive; no direct in-pore BA transport measurement is reported.
3 · Results and Discussion · Figure 1 · Linked to 3 structured results
The enhanced BA oxidation of NiCoFe-CAT is attributed to larger effective electrochemical surface area and faster charge-transfer kinetics.
Caveat: Cdl is an ECSA proxy and EIS resistance is measured in an electrochemical composite-electrode context.
6 · Results and Discussion · Figure 4d-e · Linked to 6 structured results
XPS shifts indicate electron transfer/strong interaction between Ni/Co and Fe centres, which the authors connect to improved charge transfer and BA oxidation reactivity.
Caveat: Mechanistic interpretation is inferred from XPS shifts and electrochemical kinetics, not direct electronic-structure transport measurements.
