Coumarin-Linked COF Boosts Hydrogen Production in Photocatalytic Water Splitting

The core technical claims in both long and short versions (coumarin-linked COF from CAS, 1,000× longer charge-separated lifetime, 531 mmol g⁻¹ h⁻¹ at 440 nm, 166 mmol g⁻¹ h⁻¹ >420 nm, 37.95% AQY at 405 nm, Pt cocatalyst, picosecond electron transfer) are accurately supported by recent reports and the Nature Synthesis paper. Policy/cost projections are broadly aligned but somewhat generalized. Overall, the article is trustworthy with minor over-generalizations.
