Abstract

Inthis study,manganese oxide nanoparticles/reduced graphene oxide(MnOxNPs/rGO) was used as support for strong immobilization of flavin adenine dinucleotide(FAD). A thin film of rGO cast on the electrode surface,followed by performing electrodeposition of MnOxNPs at applied constant potential of +1.4 V vs.Ag/AgCl for 200 s. Finally,FAD was electrodeposited onto the rGO/MnOxNPs film by potential cycling between 1.0 to -1.0 V in solution containing 1 mgml -1 FAD. Electrochemical properties and catalytic activity of GCE/rGOMnOxNPs/FAD toward persulfate (S2O8 2-)reduction was investigated. Under ptimized condition,the concentration calibration range,detection limit, and sensitivity were 0.1 mM–2 mM, 90 nM and 125.8 nA/mM, respectively,using hydrodynamic amperometry technique.
