Abstract
Abstract Solar‐driven selective synthesis of C 2 chemicals from CO 2 is a crucial pathway for carbon cycling, but it is limited by the high kinetic barrier of C─C coupling. This study proposes an epitaxial growth strategy for lattice‐bonded asymmetric sites. By constructing a Bi 1 ─O─Bi 2 site at the Bi 3 NbO 7 nano‐dots/Bi 3 O 4 Br nanosheet (BNO/BOB) interface to promote C─C coupling for acetic acid production, the photocatalytic conversion rate of CO 2 to acetic acid can reach 192.3 µmol·g −1 ·h −1 , with 91.4% selectivity. The apparent quantum efficiency at 380 and 400 nm reach 9.49% and 6.57%, respectively. The key mechanism originates from a cascade electron effect triggered by the interfacial Bi 1 ─O─Bi…
