Abstract
The mixture of insoluble organics and water seriously affects human health and environmental safety. Therefore, it is important to develop an efficient material to remove oil from water. In this work, we report a superhydrophobic Cu2O mesh that can effectively separate oil and water. The superhydrophobic Cu2O surface was fabricated by a facile chemical reaction between copper mesh and hydrogen peroxide solution without any low surface reagents treatment. With the advantages of simple operation, short reaction time, and low cost, the as-synthesized superhydrophobic Cu2O mesh has excellent oil–water selectivity for many insoluble organic solvents. In addition, it could be reused for oil–water separation with a high separation ability of above 95%, which demonstrated excellent durability and reusability. We expect that this fabrication technique will have great application prospects in the application of oil–water separation.
Highlights
Oil in water can reduce the purity of water, and the oily wastewater generated in daily life and industry can cause serious pollution to the environment [1,2]
Two peaks located at the binding energies of 952.5 and 932.5 eV can be attributed to Cu 2p1/2 and Cu 2p3/2, Coatings
The superhydrophobic Cu2 O mesh was prepared by a one-step reaction of red copper mesh and hydrogen peroxide without modification of any low surface energy reagent
Summary
Oil in water can reduce the purity of water, and the oily wastewater generated in daily life and industry can cause serious pollution to the environment [1,2]. The research of the separation of the oil–water mixture is of great significance and has broad application prospects. Efficient oil–water separation technology has attracted great attention [3,4,5,6,7]. The contact angles of water and diesel oil on this mesh were 156.2◦ and 0◦ , respectively, which realized the effective separation of diesel and water [8]. Many scientists have developed great interest in the application of special wettability materials in oil–water separation
