We
prepared a cost-effective, environmentally friendly carbonaceuous
oil sorbent with a lotus effect structure using a simple one-pot hydrothermal
reaction and a mild modification process. The carbonaceous oil sorbent
can rapidly, efficiently, and continuously collect oil in situ from
a water surface. This sorbent was unlike traditional sorbents because
it was not dependent on the weight and volume of the sorption material.
The sorbent was also successfully used to separate and collect crude
oil from the water surface and can collect organic solvents underwater.
This novel oil sorbent and oil-collection device can be used in case
of emergency for organic solvent leakages, as well as leakages in
tankers and offshore drilling platforms.
