10CAT-1 Film degrades glyphosate efficiently at neutral pH under ambient air, reaching about 75% degradation in 1 h with k = 0.022 min-1 and retaining 68.92% after five cycles.
Caveat: Application performance is for a paper-supported film electrode, not an intrinsic electrical-transport measurement of a free-standing MOF.
1 · Abstract · Linked to 6 structured results
ECOSAR calculations indicate that glyphosate degradation products have substantially higher LC50 values than glyphosate and reduced acute toxicity.
Caveat: Toxicity values are ECOSAR/QSAR estimates, not new biological assays; Table S4 values are now taken from the rendered SI table.

Increasing the copper nitrate concentration during film construction yields a thicker, more continuous Cu-HHTP layer with lower Raman ID/IG ratio, narrower XRD peaks and improved hydrophilicity.
Caveat: Contact-angle text and rendered figure label are inconsistent (20.0 vs 24.0 degrees for 10CAT-1); both were retained with provenance.
5 · 3.2 High Cu concentration induces crystallinity perfection · Fig. 2 · Linked to 9 structured results
The consecutive Cu-HHTP layer and reduced graphitic defects in 10CAT-1 improve electrochemical charge transfer relative to CAT-1.
Caveat: The electrochemical CV/LSV/EIS improvements are reported qualitatively; fitted resistance/current values are not tabulated.
7 · 3.4 Incrassated Cu-HHTP layer promotes the electrochemical performance · Fig. 4 · Linked to 3 structured results
Cu2+/Cu+ cycling in conductive Cu-HHTP promotes in situ H2O2 activation to hydroxyl radicals, which attack glyphosate and drive mineralisation.
Caveat: Mechanistic evidence combines ex-situ XPS, EPR and LC-MS; radical concentration is qualitative.
