Defect-Driven Reconstruction of Bismuth Nanoflowers via Precursor Engineering for Highly Efficient CO₂-to-Formate Electrochemical Reduction.

ABSTRACT: Electrochemical reduction of CO₂ represents a promising strategy for converting CO₂ into value-added chemical products. Currently, significant efforts have been devoted to developing more efficient Bi-based catalysts to reduce CO₂ to formate. However, the role of precursor defects in directing the electrochemical reconstruction of Bi-based catalysts is yet to be thoroughly investigated. Herein, a strong alkali-induced strategy, coupled with electrochemical reduction for controllable morphology and defect engineering to achieve Bi₂O₃ reconstruction with oxygen vacancies (O_v-Bi₂O₃) into defect-rich Bi nanoflowers (Bi (O_v-Bi₂O₃)) featuring small-angle grain boundaries, is r
