Yet Another Nanomaterial Does a Good Job at Oil Spill Remediation
This blog has chronicled many nanomaterials suggested for cleaning up oil spills over the years, with the most recent being an aerogel developed in China that the researchers claim to be the lightest ever produced and capable of soaking up a rather astounding 900 times its own weight in oil. This compares favorably to the current mainstay for oil spill remediation, hay, which only absorbs 3 to 15 times its weight in oil.
Now researchers at Deakin University in Australia have developed a nanosheet made of a porous boron nitride that can soak up 33 times its own weight in oil. While this weight-to-oil-ratio figure doesn't seem to stack up favorably to some other technologies, like the aerogel above, it does have some side benefits that are lacking in some of the other solutions.
Notable among them is that once the nanosheets have soaked up their share of oil, they can be cleaned and ready to be used again by merely letting them heat in ambient air for two hours. They also are hydrophobic, meaning they repel water, which allows them to float on the surface of the water and be available for easy retrieval during a clean up.
