With
the development of world oil production and the increase of
transportation, oil spillage accidents showed a rising trend, which
was not only harmful to the ecological environment but also a huge
threat to people’s health. Herein, we reported a novel kind
of linear-coated magnetic silica submicrometer materials with controlled
porosity for oil spill cleanup. The results showed that the submicrometer
composite materials with superhydrophobicity, superoleophilicity and
good magnetic response, which had a significant effect on oil absorption
and was used to absorb different oils up to 11.51 times of its own
weight. More importantly, the oil-absorbed material could be recycled
in the auxiliary magnetic field and still exhibited an excellent performance
after the 20th cycle. With a combination of simple synthesis process,
magnetic responsivity, and excellent hydrophobicity, the modified
magnetic porous silica submicroparticles have broad application prospects
as a promising absorbent.
