Covalently Bonded S‐Scheme Polymer Heterojunction for Highly Efficient Solar Hydrogen Evolution
A covalently integrated all‐organic S‐scheme heterojunction (B‐CN2@Py‐CN) establishes atomic‐level charge transport channels and a strong built‐in electric field, enabling exceptional charge separation efficiency. This molecularly engineered photocatalyst achieves a cocatalyst‐free hydrogen evolution rate of 27.9 mmol g−1 h−1 under visible light ...
