英文摘要 | Oil adsorption by porous materials is a major strategy or water purification and industrial spill cleanup; it is of great interest if the adsorbed oil can be safely recovered from those porous media. Here, direct oil recovery from fully saturated bulk carbon nanotube (CNT) sponges by displacing oil with water in controlled manner is shown. Surfactant-assisted electrocapillary imbibition is adopted to drive aqueous electrolyte into the sponge and extrude organic oil out continuously at low potentials (up to -1.2 V). More than 95 wt %) of oil adsorbed within the sponge can be recovered, via a single electrocapillary process. Recovery of different oils with a wide range of viscosities is demonstrated, and the remaining CNT sponge can be reused with similar recovery capacity. A direct and efficient method is provided to recover a from CNT sponges by water imbibition, which has many potential environmental and energy applications.; National Natural Science Foundation of China (NSFC) [11225208, 11521202, 51325202]; key subject "Computational Solid Mechanics" of China Academy of Engineering Physics; SCI(E); EI; ARTICLE; anyuan@pku.edu.cn; hlduan@pku.edu.cn; 19; 12337-12343; 8 |
