Abstract

In this manuscript we have successfully synthesized a large scale 3D dendritic α-Fe ₂ O ₃ hierarchical structure via a hydrothermal reaction. The crystallinity, composition, purity, morphology of the synthesized α-Fe ₂ O ₃ are characterized by powder X-ray diffraction (PXRD), field emission scanning electron microscopic (FESEM), energy dispersive X-ray spectroscopic (EDS). FESEM image reveals that the individual α-Fe ₂ O ₃ dendrite consists of a long central trunk with secondary and tertiary branches. For electrochemical H ₂ O ₂ sensing we have carried out cyclic voltammetry (CV), amperometric i-t measurement. It has been found that the current density vs. H ₂ O ₂ concentration calibration curve is linear in nature. The present study reveals that the dendritic α-Fe ₂ O ₃ hierarchical structure exhibits very sensitive electrochemical sensing capability towards H ₂ O ₂ reduction.
