Co-Atomic Interface Minimizing Charge Transfer Barrier in Polytypic Perovskites for CO₂ Photoreduction.

ABSTRACT: Heterojunctions, known for their decent separation of photo-generated electrons and holes, are promising for photocatalytic CO₂ reduction. However, a significant obstacle in traditional post-assembled heterojunctions is the high interfacial barrier for charge transfer caused by atomic lattice mismatch at multiphase interfaces. Here, as research prototypes, the study creates a lattice-matched co-atomic interface within CsPbBr₃-CsPb₂Br₅ polytypic nanocrystals (113-125 PNs) through the proposed in situ hybrid strategy to elucidate the underlying charge transfer mechanism within this unique interface. Compared to CsPbBr₃ nanocrystals, the 113-125 PNs exhibit a remarkable 3.6-fold increase in photocatalytic CO₂ reduction activity
