Controllable Reconstruction of β-Bi₂O₃/Bi₂O₂CO₃ Composite for Highly Efficient and Durable Electrochemical CO₂ Conversion.

ABSTRACT: The uncontrollable electrochemical reduction reconstruction, leading to the destruction of well-defined structure and subsequent low durability, is the main obstacle to the catalytic performance of Bi-based composites toward electrochemical CO₂ reduction reaction (eCO₂RR). Herein, we address this issue through construction of a novel β-Bi₂O₃/Bi₂O₂CO₃ composite, which can resist the reduction reconstruction of Bi-based materials to metallic Bi during the eCO₂RR process by modulating a more alkaline microenvironment that facilitates the formation of new Bi-O bonds. The synergistic interactions and directional electron transfer between the β-Bi₂O₃ and Bi₂O₂CO
