Description 313-319
The present work focused on the synthesis and characterization of Cr (~2, 3 & 5 wt.%) doped Fe2O3 nanoparticles with
desired electrochemical property for creatinine bio sensor applications via the extraction of Nyctanthes arbor tristis seed by facile
chemical precipitation method. The synthesized samples have dimensions of the order of 0.5 to 0.8 μm and crystallite size of the
prepared samples calculated by Powder XRD analysis using Scherer’s formula. The optical characterization of the prepared
nanomaterials showed that the band gap energy of the annealed chromium doped samples were found to be 5.74 eV by varying in
intensity by Tauc plot that established well optical nature of the synthesized compound which is also have a good concord with the
Powder XRD analysis with its crystalline nature. The FT-IR spectra clearly indicating the complete formation of Fe2O3 by
observing corresponding functional groups such as Fe=O and O=O vibrations in their respective wavenumbers. The sensing
performance of the prepared samples for creatinine was carried out using electrochemical workstation. Interestingly, the
electrochemical analysis exposed the good sensing behaviour of the Cr-doped Fe2O3 nanoparticles which displayed corresponding
redox peaks attributed to the reversible Faradaic redox reaction at the electrode surface caused by the pseudo-capacitance nature for
α – Fe2O3 nanoparticles as an active material, slightly than the double layer capacitance. Consequently the current outcomes
revealed a good sensing behaviour on creatinine for Cr-doped Fe2O3 nanoparticles synthesized by an effortless cost effective green
synthesis method.
