Synthesis And Characterisation of Green-Reduced Metal Oxide Nanoparticles Using Fungal Extracts

Abstract

Environmental concerns about current chemical processes have led to interest in eco-friendly and sustainable metal oxide nanoparticle production. This study involves a green synthesis of ZnO, CuO, and Fe₂O₃ nanoparticles using fungal extracts, providing a safe and cost-effective option. UV-Visible Spectroscopy, FTIR, SEM, and XRD confirmed nanoparticle production, functional groups, shape, and crystalline structures. The UV-Vis analysis revealed characteristic absorption peaks at 297 nm (ZnO), 320 nm (CuO), and 350 nm (Fe₂O₃), while FTIR identified key functional groups responsible for reduction and stabilization. SEM analysis showed varying particle sizes and morphologies, and XRD confirmed their crystalline nature. Statistical analysis supported strong correlations between optical and morphological features. The findings demonstrate that fungal-mediated synthesis is an efficient and sustainable approach, paving the way for potential applications in biomedicine, catalysis, and environmental remediation.
