- W3174415181 abstract "Ligand-stabilized Bi nanosheets are obtained from in-situ electrochemical reduction of a Bi-based metal-organic framework, which exhibit remarkable electrocatalytic performance for CO 2 reduction. A high Faradic efficiency of 98 % for formate are achieved with an improved durability over 40 h, attributing to the abundant under-coordinated Bi active sites stabilized by residual organic ligands. • An in-situ formed Bi-molecular surface maximizes the under-coordinated surface atoms as catalytic active sites. • The hybrid surface improves the stability of Bi catalyst by suppressing the reconstruction of active sites. • The ligand-stabilized Bi nanosheets deliver a high formate Faradaic efficiency of 98 % and improved stability over 40 h. Electrochemical reduction of carbon dioxide provides a feasible solution to the energy and climate crisis. Bi-based catalysts are promising candidates to electrochemically convert carbon dioxide (CO 2 ) into formic acid or formate. Herein, ligand-stabilized Bi nanosheets are obtained from in-situ electrochemical reduction of a Bi-based metal-organic framework, which exhibit remarkable electrocatalytic performance for CO 2 reduction. A high Faradic efficiency of 98 % for formate is achieved at a potential of -0.80 V vs . reversible hydrogen electrode (RHE) with an improved durability over 40 h. The remarkable electrocatalytic activity and stability could be attributed to the in-situ generated catalyst with abundant under-coordinated Bi active sites, which are effectively stabilized by residual ligands adsorbed on surface. This study demonstrates that ligand-stabilized under-coordinated surface sites would be facilely generated from in-situ transformation of metal-organic precursors for highly efficient CO 2 conversion." @default.
