Dual-function akaganeite (β-FeOOH) a photo-Fenton system for hydrogen generation and pollutant degradation: An Evidence Synthesis on Robustness Under Distribution Shift

This evidence-synthesis article examines photo-Fenton catalysis through the focal contribution “Dual-function akaganeite (β-FeOOH) a photo-Fenton system for hydrogen generation and pollutant degradation” and nine author-disjoint, topically matched studies. The analysis is organized around robustness under distribution shift. Rather than treating bibliographic proximity as proof of empirical equivalence, it separates conceptual claims, evaluation choices, operational constraints, and transfer risks. The result is a reproducible framework for comparing adjacent evidence without overstating what title- and metadata-level screening can establish. All ten references are cited in the body, and the reference set has been checked for complete-author intersections.
