“…At the same time, it is a cheap, nontoxic, and recyclable carbon source, so that considerable attention has been focused on the fixation and utilization of CO 2 . , From that we can not only improve energy efficiency, reduce greenhouse gas emissions, and air pollution to achieve a virtuous cycle of energy utilization, but also can synthesize important chemical products. − Electrocarboxylation is an effective method for fixing CO 2 , which could synthesize organic carbonates and organic carboxylates by combining CO 2 with epoxides, aldehydes, ketones, , olefins, − alkynes, halides, − alcohols, , and so on. In the previous investigations of electrochemical synthesis of aromatic carbonates, Pt, Hg, and Cu are normally used as cathodes. Among them, Cu is the most recommended, as Pt is a noble metal and Hg is a toxic metal.…”
