In the present study, an eco-friendly and cost-effective green synthesis route was employed for the preparation of manganese oxide (MnO) nanoparticles using castor (Ricinus communis) leaf extract as a natural reducing and stabilizing agent. The phytochemicals present in the leaf extract, such as polyphenols, flavonoids, and proteins, play a crucial role in the reduction of manganese ions and the subsequent formation of stable MnO nanoparticles without the use of hazardous chemicals. The synthesized MnO nanoparticles were characterized using X-ray diffraction (XRD) to investigate their crystalline structure, phase purity, and average crystallite size. The XRD pattern confirmed the formation of crystalline MnO with characteristic diffraction peaks matching the standard JCPDS data, indicating high purity and successful synthesis. The average crystallite size of the MnO nanoparticles was estimated using the Debye-Scherrer equation and found to be in the nanometer range. The green synthesis approach demonstrated in this work offers a sustainable and environmentally benign method for producing MnO nanoparticles with controlled crystallinity, making them suitable for potential applications in catalysis, energy storage, and environmental remediation.
