Mesoporous Carbon/α-Fe₂O₃ Nanoleaf Composites for Disposable Nitrite Sensors and Energy Storage Applications.

ABSTRACT: In this work, we report a novel hydrothermal synthesis of α-Fe₂O₃ nanoleaf-incorporated mesoporous carbon-chitosan (α-Fe₂O₃@MPC-chit) as a versatile disposable sensor for selective electrochemical detection of nitrite and for supercapacitor applications. The newly synthesized α-Fe₂O₃@MPC-chit nanocomposite was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform-infrared spectroscopy, UV, and Raman spectroscopy. The extensive physicochemical characterization reveals the strong immobilization of α-Fe₂O₃ nanoleaves within the MPC-chit composite. The electrochemical characterization with cyclic voltammetry and impedance spectroscopy using [Fe(CN)₆)]^3-/4-
