Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

Co/Mn-BTC was the most active of the Fe, Ce, Co and Cu bimetallic Mn-BTC catalysts for plasma-catalytic toluene removal.

Caveat: Performance is application-specific to the DBD reactor and reaction conditions.

p013 · 4. Conclusion · Linked to 4 structured results

CaveatSupport assessment: High

The article does not report first-hand electrical conductivity, carrier mobility, Seebeck coefficient, thermal conductivity or electrochemical device performance for the MOFs.

Caveat: The introduction states energised MOFs can show semiconductor-like characteristics, but this paper does not measure transport properties.

p002 · 1. Introduction

CaveatSupport assessment: High

Underlying data are not shared by the authors, limiting extraction of exact values from plotted curves beyond numbers reported in the text and tables.

Caveat: No network retrieval was attempted per assignment instructions.

p013 · Data availability

Phase AssignmentSupport assessment: High

The authors conclude that bimetallic M/Mn-BTC MOF materials were successfully synthesised, based on XRD, FTIR, SEM/EDS and XPS evidence.

Caveat: Exact crystallographic structures and formulae are not reported; assignments rely on comparison to literature peaks.

Structure Property LinkSupport assessment: High

A high Oads/Olatt ratio is linked to superior toluene oxidation, and the strong decrease after reaction indicates consumption or participation of adsorbed oxygen during catalysis.

Caveat: Mechanistic assignment is inferred from ex situ XPS and catalytic trends.

p012-p013 · 3.4.4; 4. Conclusion · Linked to 3 structured results

Transport MechanismSupport assessment: Medium

The authors attribute the synergistic activity of Co/Mn-BTC to Mn/Co redox cycling, enhanced electron transfer and oxygen mobility, forming Oads and active oxygen species from O3 decomposition.

Caveat: No direct electrical transport measurement was reported; electron transfer is mechanistic interpretation from redox-state changes and activity.
