A superhydrophobic-oleophilic quartz sand with WCA of 154.0 ± 1.2° and SA of 4° was developed by using the superhydrophobic nano-silica particles to treat quartz sand [21]. The obtained quartz sand presented good ability of oil-water separation. However, the preparation of superhydrophobic silica nanoparticles is a bit complicated.
