Highly sensitive nonenzymatic glucose and H2O2 sensor based on Ni(OH)2/electroreduced graphene oxide−Multiwalled carbon nanotube film modified glass carbon electrode

A new sensor of Ni(OH)2/electroreduced graphene oxide (ERGO)-multiwalled carbon nanotube (MWNT) has been fabricated by electrodepositing Ni(OH)2 nanoparticles onto ERGO-MWNT hybrid film modified glass carbon electrode (GCE). ERGO-MWNT film was coated on the electrode by dropping suspension of graphene oxide-MWNT complex onto the surface of GCE with subsequent electroreduction process. This easily prepared sensor demonstrates wide linear range, low detection limit and high sensitivity towards H2O2 and glucose detection.
