Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The ZIF-67-containing electrode shows selective non-enzymatic H2O2 sensing with minimal response to common interferents.
Caveat: Selectivity was tested against the listed species only under the reported alkaline sensing condition.
5-6 · Results and discussion · Fig. 7 · Linked to 3 structured results
Direct in-situ growth of ultrathin ZIF-67 nanosheets on Ti@TiO2/CdS is presented as superior to binder-coated MOF electrodes and to powder-cast ZIF-67 controls.
Caveat: SI control figures support the trend; numerical control slopes read from figure labels were added, while exact curve digitisation/raw data are not available.
2 · Introduction · Linked to 3 structured results
SI optimisation/control figures show the best OER kinetics for the 294 ug cm^-2, 6 h in-situ Ti@TiO2/CdS/ZIF-67 electrode, while the no-CdS and powder-cast controls have larger Tafel slopes.
Caveat: Control values are read from rendered SI figure labels rather than tabulated text or raw fitted data.
SI rendered p007-p009 · Supplementary Figures · Figs. S5-S9 · Linked to 4 structured results
The higher double-layer capacitance of Ti@TiO2/CdS/ZIF-67 indicates larger electrochemical active surface area, contributing to stronger OER activity.
Caveat: ECSA is inferred from Cdl rather than directly calculated because a specific capacitance value was not given.
4 · Results and discussion · Fig. S11 · Linked to 3 structured results
Nitrogen in the imidazole ligand shifts Co electronic structure, promotes higher-valence Co character and facilitates reversible oxygen-species chemisorption, improving OER activity.
Caveat: Mechanistic assignment is inferred from XPS peak shifts and electrochemical performance rather than directly observed operando valence changes.
5 · Results and discussion · Fig. 3 · Linked to 4 structured results
The Ti@TiO2/CdS nanowire substrate improves charge transport by carrying electrons along the 1D Ti@TiO2 nanowires to the Ti substrate and by lowering charge-transfer resistance.
Caveat: EIS support is qualitative in the main text; rendered SI Nyquist plots were inspected, but no fitted resistance values are reported.
