Abstract
Abstract Covalent organic frameworks (COFs) are highly desirable for achieving high‐efficiency overall photosynthesis of hydrogen peroxide (H 2 O 2 ) via molecular design. However, precise construction of COFs toward overall photosynthetic H 2 O 2 remains a great challenge. Herein, we report the crystalline s ‐heptazine‐based COFs (HEP‐TAPT‐COF and HEP‐TAPB‐COF) with separated redox centers for efficient H 2 O 2 production from O 2 and pure water. The spatially and orderly separated active sites in HEP‐COFs can efficiently promote charge separation and enhance photocatalytic H 2 O 2 production. Compared with HEP‐TAPB‐COF, HEP‐TAPT‐COF exhibits higher H 2 O 2 production efficiency for integrating dual O 2…
