A flexible electrochemical sensor for paracetamol based on porous honeycomb-like Ni Co-MOF nanosheets

摘要

The overdose of 4-aminophenol(AP) threatens human health,and the determination of AP is crucial.Here,we report a flexible electrochemical sensor for highly sensitive and precise determination of AP.The ultrathin honeycomblike NiCo-MOF nanosheets were in situ grown on freestanding flexible carbon cloth(CC) electrode.The porous structure among nanosheets and rich porosity of NiCoMOF shorten the transport path of electrolyte ions and reactants,ensuring fast electron transport.
