DOIAbstract
Maghemite/magnetite nanocomposite ( γ-Fe₂ O₃/Fe₃ O₄ ) was prepared via an electrochemical method using pulse alternating current and applied for electrocatalytic reduction and sensing of hydrogen peroxide. The structural and compositional analysis of the γ-Fe₂ O₃/Fe₃ O₄ was characterized by XRD, SEM, TEM and XPS. Its thermal decomposition behavior was studied using TG/DSC. The mechanism for γ- Fe₂ O₃/Fe₃ O₄ nanocomposite formation was propose
