A New Strategy towards Efficient and Recyclable Carbon‐Chloride Bond Cleavage of Environmentally Harmful Organochlorides through Electrochemical Catalysis in Non–aqueous Media

Transition metal coordinated porphyins generally exhibit effective carbon‐chloride bond cleavage of environmentally harmful organochlorides through electrochemical reductive catalysis in non‐aquaous media, but the recyclable use of the catalyst remains a challenge. In this manuscirpt, a new strategy of an efficient and recyclable C−Cl bond cleavage is described, and the structural characterization, electrochemical behaviour and electrochemical catalysis were illustrated by various techniques. It is demonstrated that the Fe 3 O 4 @SiO 2 @Co(II)porphyrin magnetic materials can be effectively used for at least 30 cycles.
