Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
HKUST-1 ED exhibits better HER metrics than HKUST-1 HT, including lower onset potential, lower overpotential at -10 mA cm^-2, and smaller Tafel slope.
Caveat: Performance is for acidic HER on composite electrodes; no intrinsic electrical conductivity data are reported.
4510 · Summary · Linked to 6 structured results
HKUST-1 ED shows better HER durability and acid structural retention than HKUST-1 HT.
Caveat: ED current retention is described qualitatively in text rather than reported as an exact percentage.
4509 · Results · Figure 3d; Figure S7 · Linked to 4 structured results
Raman spectra indicate HKUST-1 ED and HKUST-1 HT have the same crystal structure, despite XRD of the ED sample showing only carbon peaks.
Caveat: ED sample phase assignment relies mainly on Raman and microscopy because XRD lacks detectable HKUST-1 peaks.
4508 · Results · Figure 2b; Figure S2 · Linked to 2 structured results
HKUST-1 ED has smaller particles and higher Cdl/ECSA proxy than HKUST-1 HT, which the authors connect to improved HER activity.
Caveat: No BET surface-area measurement is reported; ECSA is inferred from double-layer capacitance.
4509 · Results · Figure 3c · Linked to 4 structured results
Direct electrodeposition anchors HKUST-1 nanoparticles on the current collector, giving lower catalyst/contact resistance and charge-transfer resistance than drop-cast hydrothermal HKUST-1.
Caveat: EIS is measured on composite electrodes in electrolyte and does not prove intrinsic HKUST-1 framework conductivity.
4509 · Results · Figure S8; Table S1 · Linked to 4 structured results
Electrochemical deposition is presented as a fast, mild route for preparing MOF-based catalysts directly on conductive substrates.
Caveat: Only HKUST-1 on carbon paper is demonstrated here; extension to other MOFs/substrates is prospective.
