3D rGO and rGO/TiO₂-Modified Melamine Sponges: Sorbents for Oil and Emerging Organic Pollutant Removal.

ABSTRACT: Environmental disasters resulting from the exploitation of natural resources, such as oil spills, have severe and lasting impacts on ecosystems. In this work, melamine sponges were modified with reduced graphene oxide (rGO) and titanium dioxide nanosheets (TiO₂) to develop multifunctional materials for environmental remediation. Prior to TiO₂ modification, the sponges were coated with rGO of different sheet sizes to evaluate the influence of rGO dimensions on surface coverage and material properties. Graphene oxide was reduced using ascorbic acid as a green reducing agent, and the process was accelerated in a microwave reactor. The resulting 3D material exhibited hydrophobic and oleophilic characteristics, enabling efficient and selective oil absorption from water. St
