A covalent organic framework-based type-II heterojunction (TpPa/TpDz) enables efficient photocatalytic H2O2 production in pure water. The highest and lowest occupied molecular orbitals are spatially separated, driving directional photogenerated carrier transport and minimizing recombination, therefore enhancing photocatalytic activity.
