Overview

Randomized trial demonstrates efficient CO2 reduction to formate in nitrogen-doped carbon, suggesting new catalyst designs.

Key Points

  • The aim is to develop efficient and stable electrocatalysts for CO2 electroreduction to formate.
  • Synthesized Bi/Bi2O3 nanoparticles via controlled pyrolysis of a Bi-metal-organic framework.
  • Utilized in situ spectroscopic characterization and density functional theory calculations to analyze catalyst performance.
  • Tested under high current densities in flow-cell and membrane electrode assembly configurations.
  • Achieved a formate Faradaic efficiency of 97% at −0.9 V vs. RHE.
  • Maintained high stability and selectivity during prolonged operation.
  • Revealed that a mixed-phase Bi3+/Bi0 interface optimizes charge transfer to the *COOH intermediate.
