Understanding the structure change of electrocatalysts during electrochemical CO2 reduction reaction (CO2RR) is crucial importance to illustrate structure–performance relationship. Here, reconstruction Bi–O–M (M = S, Se, or Cl) nanosheets induced by in situ dissociated chalcogenide anions toward efficient CO2RR formate reported. The surface work function and potential zero charge (PZC) metallic Bi are reduced upon anions' adsorption, facilitating regeneration active Bi–O structures reduction. Moreover, a correlation between pKb values local pH catalyst/electrolyte interface can be established. anion with smaller (S2– < Se2– Cl–) would induce more alkaline environment further promote formation structures. Among them, Bi2O2S released S2– exhibits best CO2RR-to-formate performance large current density 32.7 mA cm–2 at −0.9 VRHE H-cells, which 3 times higher than Bi2O3 without trace outperforming most reported Bi-based catalysts. In flow cell, reach 280 −0.56 96% average FEformate achieved 150 long-term test. This provides an approach regulate electrocatalytic metal through anions.

Electroreduction of carbon dioxide into readily collectable and high-value carbon-based fuels is greatly significant to overcome the energy environmental crises yet challenging in development robust highly efficient electrocatalysts. Herein, a bismuth (Bi) heterophase electrode with enriched amorphous/crystalline interfaces was fabricated via cathodically situ transformation Bi-based metal-phenolic complexes (Bi-tannic acid, Bi-TA). Compared amorphous or crystalline Bi catalyst, structure leads significantly enhanced performance for CO2 electroreduction. In liquid-phase H-type cell, Faraday efficiency (FE) formate formation over 90% wide potential range from -0.8 -1.3 V, demonstrating high selectivity toward formate. Moreover, flow large current density reaching 600 mA cm-2 can further be rendered production. Theoretical calculations indicate that interface exhibits favorable adsorption lower barriers rate-determining step compared counterparts, thus accelerating reaction process. This work paves way rational design advanced heterointerface catalysts reduction.
