Classical methods of cleaning oil spills do not give satisfactory results in removing the oil from the water, but functionalized nanomaterials show high potential to become a cost-effective, efficient, and environmentally friendly solution. Among the existing methods of cleaning oil stains from water, the use of various adsorptive materials, such as silicon dioxide, titanium dioxide, zinc oxide and aluminum oxide are present. These materials are non-biodegradable and represent a high risk of secondary pollution. The invention of researchers at the University of Maribor is based on the problem of how to synthesize nanoparticles so that they will have physicochemical properties that will be useful for adsorption of oil stains and spills in water.
