Abstract
The present work reports the successful natural synthesis of Fe₂O₃ and CuO nanoparticles (NPs) using sugarcane juice as a reducing and capping agent. The good crystallinity and functional groups of these NPs have been confirmed by x-ray diffraction and Fourier transform infrared spectroscopy, respectively. Besides, the average crystallite size has been calculated to be 18.73 and 16.6 nm for Fe₂O₃ and CuO NPs, respectively. Scanning Electron Microscopy investigation showed nanostructures with irregular shapes of randomly oriented particles. The dielectric properties have been studied at room temperature within the frequency range from 4 kHz to 1 M Hz. Typical behavior of the dielectric constant, dielectric loss, and total conductivity upon varying the applied frequency has been observed. CuO NPs have high dielectric properties and conductivity as compared to Fe₂O₃NPs. The results revealed that Fe₂O₃ and CuO NPs are promising candidates for use in various applications including energy storage devices, gas sensors, and communication systems.
