摘要
Considering the futuristic importance of hydrogen for the production of sustainable fuels; in this study, we developed an organic-inorganic hybrid semiconductor material comprising a heterogeneous interface between linear-conjugated polymers (PF3T) and titanium dioxide (TiO 2 ) nanoparticles (denoted as PF3T@TiO 2 ) for visible light-driven hydrogen production via water splitting. The as-developed PF3T@TiO 2 composite 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 TiO 2 and effectively extends the lifetime of the photogenerated carriers of PF3T by several orders. Consequently, as compared to PF3T, the H 2 production yield of PF3T@TiO 2 is improved by 36-fold (11,783 μmol g -1 h -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.
