Application RelevanceSupport assessment: Medium
Ni-AEs retain H2 production under seawater and sunlight conditions, but the SI condition labels are internally inconsistent.
Caveat: Main text/Fig. 2d and SI Tables S7/S8 disagree on seawater versus sunlight labelling. | Schema-normalised claim_type from 'application_performance' to 'application_relevance'; the original controlled-label wording is retained here.

Application RelevanceSupport assessment: High
Ni-Ca gives higher photocatalytic H2 evolution than Ni-Sr under the standard, seawater and sunlight assignments, consistent with its improved electron/proton transport and hydrophilicity.
Caveat: Main text/Fig. 2d and SI Tables S7/S8 disagree on the seawater versus sunlight labels; the extraction follows the main-text/figure assignment. | Schema-normalised claim_type from 'application_performance' to 'application_relevance'; the original controlled-label wording is retained here.

Application RelevanceSupport assessment: Medium
Ni-AEs are structurally stable during photocatalytic recycling, with activity remaining near 90% after four cycles.
Caveat: Recycling and pH-stability support includes figure/caption evidence; no raw diffraction data are supplied.

Ni-Sr is treated as an isostructural Sr analogue based on PXRD similarity and metal-ratio evidence.
Caveat: No separate full SCXRD table for Ni-Sr was present in the local documents. | Schema-normalised claim_type from 'structure' to 'phase_assignment'; the original controlled-label wording is retained here.

Structure Property LinkSupport assessment: Medium
Redox-active NiS clusters mimic hydrogenase active centres, while CaO/SrO clusters and hydrogen-bonding chains create a hydrophilic microenvironment that supports electron/proton transport and hydrogen evolution.
Caveat: The microenvironment mechanism is supported by structure, hydrogen bonding and transport/application correlations rather than a direct operando mechanistic measurement.

PL quenching and EPR evidence support faster photo-induced electron transfer for Ni-Ca than Ni-Sr.
Caveat: PL constants are read from plotted Stern-Volmer equations; EPR comparison is partly qualitative. | Schema-normalised claim_type from 'photophysics_mechanism' to 'transport_mechanism'; the original controlled-label wording is retained here.
