摘要: Abstract The present study reports on an easy preparation of poly(pyronin Y)/graphene (poly(PyY)/graphene) nanocomposites thin films indium tin oxide coated glass substrates (ITO). poly(PyY)/graphene are prepared by a novel method consisting three steps; ( i ) graphene (GO) ITO spin-coating method, ii self-assembly PyY molecules from aqueous solution onto the GO film, iii surface-confined electropolymerization (SCEP) adsorbed film. as-prepared characterized using electroanalytical and spectroscopic techniques. Afterwards, graphene-based polymeric dye film is used as electrode in electrochemical cell. Its performance tested for detection nitrite. Under optimized conditions, electrocatalytical effect through oxidation nitrite better than that ITO.
