摘要：Constructing efficient heterojunctions with accelerated charge separation and directional carries migration is crucial for high-performance photocatalytic hydrogen evolution. Herein, a 1D CdS/TpPa-COF S-scheme heterojunction is rationally constructed via an in situ growth strategy under mild conditions, in which TpPa-COF is uniformly anchored onto CdS nanorods (NRs) to form an intimate interface. Benefiting from the well-defined 1D architecture and strong interfacial electronic coupling, the CdS/TpPa-COF heterostructure exhibits significantly enhanced efficient charge separation, and directional charge transport driven by an internal built-in electric field. The optimized CdS/TpPa-COF photocatalyst delivers a remarkable photocatalytic hydrogen evolution rate of 165 mmol & centerdot;g-1 & centerdot;h-1, which is substantially higher than those of pristine CdS and TpPa-COF. Notably, excellent hydrogen production performance is also achieved under real sunlight irradiation. The results reveal that spontaneous electron transfer induces band bending and establishes an S-scheme charge-transfer pathway, preserving strong redox potentials and enhancing the photocatalytic hydrogen evolution performance. This work highlights the promise of dimensionally regulated 1D COF-based heterojunctions for advanced solar-to-fuel conversion systems.
