Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The reduced CoPIZA/FTO film catalyses carbon tetrachloride reduction, and the observed catalysis is assigned to intact MOF.
Caveat: Catalysis is demonstrated qualitatively as proof of concept; no turnover frequency or current density was reported.

CoPIZA/FTO is stable during CV/spectroelectrochemistry and prolonged electrolysis at -1.04 V, but degrades during prolonged -1.45 V electrolysis.
Caveat: The -1.45 V degradation is inferred to involve framework-node reduction and cluster breakdown.

CoPIZA grows directly on the FTO substrate under solvothermal conditions and is confirmed by XPS, PXRD and SEM.
Caveat: PXRD has additional 6.4 and 7.2 deg peaks attributed to multiple diffraction or unknown impurities.

CoPIZA/FTO is semiconducting in dark conductivity magnitude but is not necessarily a semiconductor in the band-structure sense.
Caveat: Interpretation is based on conductivity magnitude and framework bonding arguments, not a direct band-structure measurement.
3 · Results and Discussion · Figure S3 · Linked to 1 structured result
Charge transfer through CoPIZA/FTO is proposed to occur by a redox hopping mechanism rather than band conduction.
Caveat: The apparent diffusion coefficient combines electron and ion transport; individual components were not separated.
