The use of eco-friendly and sustainable materials in the synthesis of nanoparticles for Environmental Remediation has gained increasing attention in recent years. This study focuses on the natural synthesis of copper oxide nanoparticles (CuO NPs) using plant extracts from Amorphophallus Paeoniifolius Tuber and Adenanthera Pavonina Leaves for the removal of dyes from industrial effluents. The green synthesis of CuO NPs using plant extracts as reducing and capping agents has been proven to be a simple, cost-effective and environmentally friendly approach. The synthesized CuO NPs were characterized using spectroscopy, X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy, revealing their crystalline structure, surface chemistry, surface area, and morphological features. The CuO NPs showed excellent photocatalytic and adsorption properties for the removal of dyes from industrial effluents. Their optical and electronic properties make them suitable as catalysts, photocatalysts, and adsorbents for heavy metal removal and water/wastewater treatment applications. Furthermore, the CuO NPs exhibited antibacterial activity, antioxidant activity, and biocompatibility, indicating their potential for biomedical applications. The biogenic synthesis of CuO NPs using plant extracts has shown promise as a green chemistry approach, providing a sustainable and renewable method for producing nanoparticles for environmental remediation and other applications. This study highlights the potential of natural synthesis approaches for the development of functional nanomaterials with tunable properties and surface chemistry for a wide range of applications.
