Peripheral environmental effect for the electrochemical reduction of 1,2-dichloroethane over a single Co–N4 site

Abstract

The role of remote nonmetallic species remains underexplored for 1,2-dichloroethane (DCE) electrochemical dechlorination over single-metal sites. We demonstrated that a peripheral conjugated structure and nitrogen atoms accelerate the transformation of *CH₂CH₂Cl to *CH₂CH₂ and ethylene desorption. CoPc achieved an FE_ethylene of 95.19 ± 0.02% and a 75.8-fold increase in J_ethylene.
