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

Key Points

• The aim is to develop a heterostructure that enhances hydrogen peroxide production through improved charge separation and light absorption.
• Embedded Cs2AgBiBr6 perovskites in hollow scaffold to form a heterojunction.
• Conducted experiments to measure dual-channel hydrogen peroxide production via ORR and WOR.
• Analyzed charge separation and light absorption efficiency.
• Achieved a hydrogen peroxide production rate of 3500 µmol g−1 h−1.
• Reported an AQE (apparent quantum efficiency) of 9.66%.
