Nanomaterials made from metal oxides play an important role in nanotechnology because they enhance catalytic efficiencies together with electrical and magnetic properties. The improved resilience combined with the super magnetic nature of Fe3O4 (Iron Oxide) and similar metal oxide nanoparticles enables extensive use across biomedicine, environmental remediation and industrial catalytic operations. The integration of iron oxide with tungsten oxide nanoparticles improves photo catalytic performance. The conversion of nanoparticles into nanocomposites generates major structural alterations including enlarged particle dimensions and unique shape structures together with altered geometrical structures. This study utilizes advanced image processing techniques to interpret Fe3O4 nanoparticles and Fe3O4–WO3 (Iron Oxide–Tungsten Trioxide) nanocomposites structural properties by analyzing SEM image data and focuses on extracting and analyzing the structural characteristics such as size, shape, aspect ratio and solidity. Analysis of Fe3O4 nanoparticles shows that nanoparticles are elliptical in shape with most nanoparticles size ranges between 51 and 100 nm but Fe3O4–WO3 nanocomposites are polygonal in shape and size exceeding 200 nm. This research highlights the importance of structural analysis in understanding nanomaterial properties and optimizing their applications.
