Crafting double perovskites/hollow conjugated microporous polymer heterostructure for dual-channel H 2 O 2 production

Cs 2 AgBiBr 6 perovskites were embedded in a hollow scaffold to form a heterojunction, which enhances charge separation and light absorption, enabling dual-channel H 2 O 2 production via ORR and WOR. It achieves a rate of 3500 µmol g −1 h −1 and 9.66% AQE.
