Green Synthesis of Manganese Oxide Nanoparticles

Green synthesis of manganese oxide nanoparticles employs biological extracts—typically from plants, fungi or bacteria—as both reducing and capping agents, enabling particle formation under mild, environmentally benign conditions. This approach obviates the need for harsh chemicals and high temperatures, instead harnessing phytochemicals or microbial metabolites to convert manganese precursors into nanoscale oxides with controlled size and morphology. Resulting particles often exhibit high surface area, tunable porosity and surface functionalisation inherited from the biological matrix. These features confer enhanced catalytic, electrochemical and biomedical performance, while minimising ecological impact. Research has explored a variety of extracts, process parameters and post-synthesis treatments to optimise crystallinity, dispersion stability and application-specific properties, positioning green-synthesised MnOx nanomaterials as sustainable candidates for energy storage, environmental remediation and health-related technologies.
