ABSTRACT
A metal-organic framework (MOF)-conductive polymer
composite film was constructed from PCN-222(Fe) nanoparticles and PEDOT:PSS
solution by simple drop-casting approach. The composite film was tested as an
electrocatalytic device for oxygen reduction reaction (ORR). The combination of
PCN-222(Fe) MOF particles and conductive PEDOT matrix facilitates electron
transfer in the composite material and improves the ORR performance of
PCN-222(Fe). Levich plot and H2O2quantification
experiment show that PCN-222(Fe)/PEDOT:PSS film mainly
catalyzes two-electron oxygen reduction and produces H2O2.
