Engineering spatially separated redox sites in donor–acceptor polymers for enhanced hydrogen peroxide photosynthesis

Abstract

Herein, two conjugated polymers are constructed, achieving an H₂O₂ production rate of 6668.3 μmol g⁻¹ h⁻¹. The exceptional performance originates from the synergistic effect of the donor–acceptor (D–A) structure achieving spatial separation of the redox sites, thereby promoting performance. This work provides a novel approach for the structural optimization of photocatalysts.
