外文摘要：Waste polyolefin plastics,accounting for 50％of all plastic waste,represent a tremendously unexploited carbon source.Efficiently upcycling polyolefin waste into value-added carbon materials for waste wa-ter treatment avoiding using noble metals is challenging but economically and environmentally sustain-able.In this work,MAX-Ti3AlC2 supported Fe selectively catalyzes polyolefin into few-layered graphene in 5 min under microwave treatment.Graphene and MAX supported Fe(Fe@MLC)can completely(99.9％)degrade chloramphenicol(CAP)within 60 min,retain robust after 10 cycles and work efficiently at a wide pH range(3.87-13.03),avoiding the usage of noble metal.Moreover,the electrochemical active sur-face area(ECSA)of Fe@MLC is 2.7 times higher than that of commercial Pt/C.This work provides a cheap and efficient catalyst that promotes deconstruction of plastic wastes and indirectly degrades antibiotics thereby realizes the treatment of waste water with waste plastic.
