Recyclable carbon nanotube sponges for oil absorption

Electro-oxidation of perfluorooctanoic acid by carbon nanotube sponge anode and the mechanism

“…2) confirms that the surface of untreated CNT sponge is indeed hydrophobic (Gui et al, 2011). The water contact angle of acid treated CNT sponge is 26.17°, much smaller than the untreated one (Fig.…”

Recyclable TiO2/carbon nanotube sponge nanocomposites: Controllable synthesis, characterization and enhanced visible light photocatalytic property

“…CNT sponge have been attractive photocatalyst carriers because of their large surface area, special aperture structure, high chemical stability and good electron conductivity [15][16][17][18][19] n range of solvents with excellent selectivity, recyclability, and their absorption capacities up to 180 times their own weight, two orders of magnitude higher than activated carbon. This strong absorptive capacity will enhance the photocatalytic property.…”

“…They can also be used for the removal of chemical contaminants such as heavy metals or organics [36]. CNTs have been used as a sponge for oil during oil spill; they have great sorption capacity and the absorbed oil can be recovered by squeezing or be converted to heat by burning the oil within sponges [37].…”
