Abstract
In this study, we developed a novel melamine sponge with bean-shaped CuO nanoparticles (MS/CuO) via a hydrothermal method. The unique nanostructure combined with the sponge's porous structure and CuO's hydrophobicity achieved 98 % separation efficiency along with excellent durability and recyclability. Additionally, the bean-shaped nanostructure along with notable photothermal properties contributed to superior photocatalytic degradation of RhB with 98 % efficiency. This integration of hydrophobic absorption and photothermal photocatalysis into a single material highlights the dual-functionality of MS/CuO as a promising solution for oil-water separation.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
