Electrochemical sensor and photocatalytic studies of ferrite nanoparticle using different fuels via green approach

The solution combustion process and environmentally acceptable green fuels, including plant root extracts from Flacortia indica and Aloe vera, were used to make a nanostructured nickel ferrite (NiFe2O4). We used X-ray diffraction (XRD) to find the crystallinity of the produced ferrite nanoparticles, Field Emission scanning electron microscopy (FE-SEM) to examine the surfaces, and energy dispersive X-ray diffraction (EDAX) to find the elements. The NiFe2O4 sample was subjected to electrochemical testing, which included electrostatic charge and discharge (GCD) experiments with electrodes submerged in a 0.1 M HCl electrolyte and measurements of AC impedance. The sample was used to build chemical sensors for arsenic trioxide and mercuric acetate. Thanks to their capacity to be magnetically retrieved, aloe vera-mediated combustion of NiFe2O4 NPs degraded 98.4 percent of the AR-88 dye after 90 min, whereas combustion of plant root extract under UV light degraded 84.4 percent. The increased emphasis on research that this comparison study sparked led to the production of high-quality, repeatable materials made of bio-composite reagents that are non-toxic and environmentally friendly.
