Abstract

Functional metal oxide nanocrystals have been extensively studied over the last decade for their unique new properties suitable for a broad spectrum of downstream applications. Of these, iron oxide nanoparticles are important materials because of their biocompatibility, catalytic activity, and low toxicity. They have significant application in various fields such as cancer therapy drug therapy, magnetic resonance imaging, high density magnetic storage devices, rechargeable lithium batteries, gas sensors and biosensors. Pure alpha-Fe₂O₃ and alpha-Fe₂O₃ doped Bi and Co powders were synthesized by the hydrolysis method. The structure and morphology of the samples were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). A very detailed study on electrical and dielectric properties to classify the material in its range of applications: first to produce hydrogen by photo electrolysis, using as electrodes (photo anode); secondly the gas detectors in ferrite bismuth in our case humidity sensor in the oil industries.
