Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

NiZrCu-BDC outperforms Ni-BDC and NiZr-BDC for liquid-product photocatalytic CO2 reduction.

Caveat: Application performance rather than intrinsic electrical transport.

p006 · Results and Discussion · Figure 5 · Linked to 6 structured results

Phase AssignmentSupport assessment: Medium

NiZrCu-BDC retains morphology and crystal structure after five photocatalytic cycles.

Caveat: Based on post-reaction XRD, XPS, TEM and EDS figures; no long-term ageing data.

Structure Property LinkSupport assessment: Medium

The ultra-thin NiZrCu-BDC nanosheet shortens the electron transport path and supports higher photocatalytic activity.

Caveat: No direct DC conductivity measurement was reported.

p007 · Conclusions · Linked to 3 structured results

Transport MechanismSupport assessment: High

Zr and Cu doping enriches electron density at Ni sites, promoting CO2 chemisorption and COOH*/CHO formation.

Caveat: Supported by spectroscopy trends and DFT models.
