Özet This study presents hydrogen peoxide determination using a new electrochemical sensor based on Fe3O4 functionalized graphene oxide (Fe3O4-APTES-GO). Fe3O4-APTES-GO was synthesized by a two-step process. First, Fe3O4 was modified by (3-aminopropyl) triethoxysilane to introduce amino groups on the surface of graphene oxide(GO). Second, APTES-Fe3O4 was reacted with the carboxylic groups of GO by an activating agent N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride to form a new material called as Fe3O4-APTES-GO. The electrocatalytic activity of Fe3O4-APTES-GO towards electrooxidation of H2O2 was described by using cyclic voltammetry technique.
