Peripheral Environmental Effect for the Electrochemical Reduction of 1,2-Dichloroethane over Single Co-N4 site

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 FEethylene of 95.19 ± 0.02% and a 75.8-fold increase in Jethylene.
