Abstract

In the current era, green synthesis stands out as the optimal approach for nanoparticle production, owing to its myriad advantages over traditional methods. Copper oxide nanoparticles (CuONP) using botanical extracts possess distinctive attributes ascribed to the phytochemicals of the extracts. These extracts can increase and maintain stability and modify the dimensions and morphology of CuONP. This green synthesis process is notable for its environmental compatibility, economic efficiency, and broad applicability, particularly in catalysis and biomedical domains. The present investigation explores synthesizing CuONP using the extract from Azadirachta indica (A. indica) seeds as a stabilizing and reducing agent. The CuONP prepared was characterized using X-ray diffraction, which revealed a mean particle size between 35 nm. Fourier Transform Infrared spectroscopy confirmed the presence of copper oxide evidenced by the stretching absorptional vibrations of functional groups. High-Resolution Transmission Electron Microscopy (HRTEM) and Scanning Electron Microscopy (SEM) evaluated the nanoparticles' morphology. The findings significantly contribute to the expanding knowledge base on eco-friendly approaches to nanoparticle synthesis, emphasizing the diverse potential applications of CuONP synthesized through this environmentally conscious method.
