Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The paper does not report direct electrical-transport or thermoelectric quantities for the MOFs; electron transfer is discussed from CV and catalytic mechanism evidence.
Caveat: Absence based on reading the main article and supplied SI text.
3 and 10 · 2.3 Catalyst characterization; 3.5 Mechanism investigation · Fig. 6d · Linked to 1 structured result
Co/Ni-MOF retained high activity over four catalytic cycles but showed metal leaching and slight structural changes, so long-run stability still needs improvement.
Caveat: Leaching values are ranges; value_numeric midpoints are supplied only for machine filtering.
7 · 3.4 Reusability and stability of Co/Ni-MOF · Fig. 4; Fig. S9; Fig. S10 · Linked to 5 structured results
The Co/Ni-MOF catalytic ozonation system produced 13 detected atrazine transformation products and the authors proposed three major pathways involving dealkylation, dechlorination-hydroxylation, alkylic oxidation, alkylic hydroxylation and olefination.
Caveat: Pathway topology is author-proposed from UPLC-MS/MS intermediate assignments rather than independent kinetic isolation of every step.
10-11 · 3.6 Degradation pathways analysis of atrazine · Fig. 7; Table S2 · Linked to 14 structured results
O2-, 1O2 and OH were identified as the main reactive species in the Co/Ni-MOF catalytic ozonation system.
Caveat: OH was inferred from DMPOX formation and TBA quenching rather than a simple direct DMPO/OH peak.
1 and 7-8 · Abstract; 3.5 Mechanism investigation · Fig. 5; Fig. 6a · Linked to 4 structured results
Surface hydroxyl groups and acid sites are proposed as dominant catalytic sites where ozone is adsorbed and converted to reactive oxygen species by electron transfer.
Caveat: Acid-site amounts were not quantified because py-IR signals were disturbed by skeleton background.
8 · 3.5 Mechanism investigation · Fig. 1; Fig. 6b; Fig. S7 · Linked to 4 structured results
Co/Ni-MOF outperformed the single-metal Co-MOF and Ni-MOF controls for catalytic ozonation of atrazine under the base conditions.
Caveat: The paper is an application/catalysis study, not a direct electrical-transport study; no conductivity values were reported.
5 · 3.2 Catalytic ozonation activity for atrazine · Fig. 2 · Linked to 3 structured results
The authors attribute the superior Co/Ni-MOF performance partly to better electron-transfer efficiency and electron-density redistribution between Co and Ni.
Caveat: The evidence is qualitative CV and XPS binding-energy shifts; no quantitative transport measurement was reported.
