Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ag-MOF-NWs show practical HER stability, with small LSV change after 1000 CV cycles and retained morphology/chemical states after electrolysis.
Caveat: The paper reports 1000 CV cycles and post-HER characterisation, but SI notes long-term stability testing could not be performed because the 200 uL electrolyte is continuously consumed.
5 · Electrocatalytic HER Performances · Figures S15-S19 · Linked to 2 structured results
The Ag-MOF-NWs are single-crystalline Ag-BHT nanowires with homogeneous Ag and S distribution.
Caveat: SI captions and rendered line-scan/OM pages are available, but raw image files/data are not supplied.
3 · Synthesis and Characterization of Materials · Figure 3 · Linked to 4 structured results
Vertical Ag-MOF-NW arrays outperform film and microfilm-wire controls for HER, with lower overpotentials, lower Tafel slope, higher TOF/Cdl and lower Rct.
Caveat: Some comparison values are read from main-text figure labels; SI comparison Table S2 is available in the rendered SI; external literature rows were not treated as first-hand results.
5 · Electrocatalytic HER Performances · Figure 5 · Linked to 5 structured results
The superhydrophilic and superaerophobic vertical NW morphology improves electrolyte transport and H2 bubble release, exposing active sites under HER conditions.
Caveat: SI provides FEA boundary/solver details, but raw COMSOL files and any movies/raw microscopy are not supplied.
7 · Superhydrophilic and Superaerophobic Structure · Figures 6 and 7 · Linked to 4 structured results
Ag-BHT MOF morphology evolves from continuous film to microfilm-wire assemblies to vertical nanowire arrays through in-plane self-limiting growth followed by out-of-plane epitaxial growth at the liquid-liquid interface.
Caveat: SI provides recipe conditions; mechanistic assignment is inferred from morphology evolution at 1, 3 and 12 h, supporting SEM series and rendered SI figures.
3 · Synthesis and Characterization of Materials · Figure 2g-i · Linked to 1 structured result
The Ag-BHT MOF is electronically conductive/metallic or degenerate semiconducting, supporting efficient electron transfer for HER.
Caveat: Conductivity is directly reported for the film sample; NW electronic behaviour is additionally inferred from band-structure modelling and shared framework chemistry.
