Hydrodechlorination of Dichloromethane by a Metal‐Free Triazole‐Porphyrin Electrocatalyst: Demonstration of Main‐Group Element Electrocatalysis**

Abstract In this work, the electrocatalytic reduction of dichloromethane (CH 2 Cl 2 ) into hydrocarbons involving a main group element‐based molecular triazole‐porphyrin electrocatalyst H2PorT8 is reported. This catalyst converted CH 2 Cl 2 in acetonitrile to various hydrocarbons (methane, ethane, and ethylene) with a Faradaic efficiency of 70 % and current density of −13 mA cm −2 at a potential of −2.2 V vs. Fc/Fc + using water as a proton source. The findings of this study and its mechanistic interpretations demonstrated that H2PorT8 was an efficient and stable catalyst for the hydrodechlorination of CH 2 Cl 2 and that main group catalysts could be potentially used for exploring new catalytic reaction mechanisms.
