Hybrid Structured Photothermal Superhydrophobic Copper Foam for Fast Adsorption of Highly Viscous Crude Oil
Industrial oily wastewater and marine oil spill accidents have caused great damage to the global ecological environment, and there is a requirement for materials that can effectively separate and collect oil. Here, based on copper oxide, cuprous oxide (Cu2O), silver (Ag), and polydimethylsiloxane, a kind of superhydrophobic and superoleophilic PDMS@Ag@CuO/Cu2O@cf (copper foam) with good photothermal performance was prepared by alkali etching and redox reaction. Benefiting from its selective adsorption of water or oil, this PDMS@Ag@CuO/Cu2O@cf can not only rapidly adsorb organic solvents (such as dichloromethane and n-hexane) but also exhibit good separation performance for oil-in-water emulsions. In addition, the prepared copper foam can generate abundant heat under the irradiation of sunlight, which can accelerate the adsorption rate of viscous crude oil by reducing its viscosity. This photothermal superhydrophobic copper foam has potential in the treatments of ocean oil spills and oily wastewater in daily life.
期刊介绍：
Langmuir is an interdisciplinary journal publishing articles in the following subject categories:
Colloids: surfactants and self-assembly, dispersions, emulsions, foams
Interfaces: adsorption, reactions, films, forces
Biological Interfaces: biocolloids, biomolecular and biomimetic materials
Materials: nano- and mesostructured materials, polymers, gels, liquid crystals
Electrochemistry: interfacial charge transfer, charge transport, electrocatalysis, electrokinetic phenomena, bioelectrochemistry
Devices and Applications: sensors, fluidics, patterning, catalysis, photonic crystals
However, when high-impact, original work is submitted that does not fit within the above categories, decisions to accept or decline such papers will be based on one criteria: What Would Irving Do?
Langmuir ranks #2 in citations out of 136 journals in the category of Physical Chemistry with 113,157 total citations. The journal received an Impact Factor of 4.384*.
This journal is also indexed in the categories of Materials Science (ranked #1) and Multidisciplinary Chemistry (ranked #5).
