Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The combined B-g-C3N4/ZIF-8 electrode delivered the most negative dark and light LSV current densities among the four tested electrodes.
Caveat: The study fixed the boron, ZIF-8 and g-C3N4 ratios and did not optimise composition.

The paper evaluates PEC CO2-reduction electrodes by CV, EIS and LSV, but does not report CO2-reduction product analysis.
10 · 4 Conclusions · Linked to 1 structured result
ZIF-8 hybridisation occurred on the surface of g-C3N4 and B-g-C3N4, as indicated by ZIF-8 XRD peaks and Zn-N FTIR bands.
Caveat: No isolated pristine ZIF-8 control was synthesised or measured in this paper.
4 · 3.1.1 X-ray diffraction (XRD) · Fig. 3 · Linked to 4 structured results
ZIF-8 incorporation strongly influenced light response and increased light-condition LSV current density compared with pristine g-C3N4.
Caveat: Application response is current density only; no CO2 reduction product analysis was recorded.
9-10 · 3.2.3 Linear sweep voltammetry (LSV) · Table 4 · Linked to 3 structured results
Boron doping strongly increased electrochemical response/current in CV relative to pristine g-C3N4.
Caveat: Authors report electro-response from CV rather than direct electronic conductivity measurement.
