Abstract

Two isostructural MOFs with coordination of different halogen ions (Cl⁻ and Br⁻), namely NNU-17 and NNU-18, were utilized to reveal the influence of different electron-withdrawing halogen anions on ECR performance. The performance difference between them mainly originates from the different abilities of adsorption and activation of CO₂ by halogen ions.
