چکیده انگلیسی
α-Fe2O3 Micro-/Nanorods were synthesized via a co-precipitation method at room temperature. The obtained products were characterized by XRD, SEM, and BET techniques. XRD analysis showed the formation of α-Fe2O3 Micro-/Nanorods. The nitrobenzene sensing of α-Fe2O3 Micro-/Nanorods-modified glassy carbon (GC) electrode was characterized using a cyclic voltammetric (CV) electrochemical technique. The CV curves exhibited redox peaks with a detection limit of 30.4 ppb. Ip was found to be linearly co-related to nitrobenzene (NB) concentration (R2=0.9916). A substantial enhancement in cathodic peak current (C1), and sensitivity (~446 nA/µM) was observed for the α-Fe2O3 Micro-/Nanorods-modified GC electrode than those of bare electrodes.
