Author interpretations and caveats

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

CaveatSupport assessment: High

Extending sulfurisation to 8 h causes structural loss, particle growth and aggregation, reducing electrocatalytic activity and DSSC performance.

11988 · Results and discussion · Fig. 1 · Linked to 3 structured results

Composite RoleSupport assessment: Medium

The amorphous carbon matrix forms a conductive scaffold that improves electron pathways while supporting CoS2 catalyst particles.

Caveat: The paper reports impedance/device evidence and qualitative mechanism, but no standalone electronic conductivity measurement.

Phase AssignmentSupport assessment: High

Annealed CoS2_4 h nanocages contain cubic CoS2 nanocrystals embedded in amorphous carbon.

Caveat: As-prepared CoS2_4 h before annealing is described as amorphous in XRD.

Structure Property LinkSupport assessment: High

Four hours of sulfurisation is optimal, producing CoS2/carbon nanocages with the best PCE, lowest resistance and highest limiting current among the tested samples.

Caveat: Optimisation was only over 1, 2, 4 and 8 h sulfurisation times.

Transport MechanismSupport assessment: High

Pristine ZIF-67 CE has poor electrical conductivity and low electrocatalytic activity, leading to the lowest DSSC performance.

Caveat: No direct electronic conductivity value is reported; inference is based on device and impedance data plus author statement.
