文摘

•: Four new bionic photocatalysts (1–4) with [2Fe2S] model complexes were reported.
•: H₂ evolution of 1–4 was evaluated, the max H₂ yield reached 52.9 ± 1.6 TON (vs. 4).
•: Inactivity of system was mainly due to photo-degradation of EBS²⁻ and catalyst (1–4).
•: Reduced Fe^IFe⁰ species could be formed by ET from ^1*EBS²⁻ to Fe^IFe^I.
•: The effect of [2Fe2S] complexes’ structure on H₂ production mechanism was discussed.
