Linear conjugated polymer photocatalysts are still hampered by challenges involving low charge separation efficiency and poor water dispersibility, which crucial factors during the photocatalytic splitting process. Herein, we synthesized Poly thieno[3,2-b]thiophene (PTT) nanoparticles with excellent visible light response characteristic. Subsequently, constructed gun–bullet model PTT/graphitic carbon nitride (PTT/g-C3N4) heterojunctions for hydrogen production, where PTT good characteristic serves as bullets g-C3N4 dispersibility guns. The as-prepared PTT/g-C3N4 show greatly accelerated production performance. Specifically, 10PTT/g-C3N4 demonstrates extraordinary performance, reaching 6.56 mmol g−1 h−1 (2 wt% Pt loading, 0.1 M AA sacrificial agent, λ > 420 nm), calculated to be 15.3 22.6 times those of g-C3N4, respectively. Mechanistic studies reveal that significantly improved performance is ascribed transfer, originates from C…S/N…S noncovalent interactions among g-C3N4. act an efficient interface transmission channel (ICTC), accelerating steady stream excited electron transfer lowest unoccupied molecular orbital (LUMO) proposed here provide a practical strategy achieving exceptional combining in polymer/polymer via interactions.
