In this work, the electrocatalytic reduction of dichloromethane (CH Cl ) into hydrocarbons involving a main group element-based molecular triazole-porphyrin electrocatalyst H2PorT8 is reported. This catalyst converted CH Cl in acetonitrile to various hydrocarbons (methane, ethane, and ethylene) with a Faradaic efficiency of 70 % and current density of -13 mA cm 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 Cl and that main group catalysts could be potentially used for exploring new catalytic reaction mechanisms.
在这项工作中，报道了使用一种基于主族元素的分子三唑 - 卟啉电催化剂H2PorT8将二氯甲烷（CH₂Cl₂）电催化还原为碳氢化合物。该催化剂在乙腈中将CH₂Cl₂转化为各种碳氢化合物（甲烷、乙烷和乙烯），在相对于Fc/Fc⁺为 -2.2 V的电位下，以水作为质子源时，法拉第效率为70%，电流密度为 -13 mA cm⁻²。该研究的结果及其机理解释表明，H2PorT8是CH₂Cl₂加氢脱氯的高效且稳定的催化剂，并且主族催化剂有可能用于探索新的催化反应机制。
