Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.
