The as-developed PF3T@TiO2composite exhibits a strong electron coupling between the terthiophene groups of PF3T and the oxygen atoms at the heterogeneous interface. Such a phenomenon induces an electron injection to TiO2and effectively extends the lifetime of the photogenerated carriers of PF3T by several orders. Consequently, as compared to PF3T, the H2production yield of PF3T@TiO2is improved by 36-fold (11,783 μmol g-1h-1), which outperforms all the existing hybrid materials in similar configurations. We envision current findings to be a strong foundation for further exploration of noble-metal free materials for photocatalytic hydrogen production. © 2022 American Chemical Society.
