Abstract
Nanocomposites include boron nitride doped with a metal, where the boron nitride doped with a metal is catalytically active for degrading a perfluoroalkyl substance. Methods of making nanocomposites include forming a mixture by adding a salt comprising a metal cation to a powder comprising boron nitride; forming a dispersion by adding the mixture to a eutectic solvent; and reacting the metal with the boron nitride to form a product comprising the nanocomposite by heating the dispersion. Methods of treating a perfluoroalkyl substance include contacting the perfluoroalkyl substance with a nanocomposite comprising boron nitride doped with a metal; and degrading the perfluoroalkyl substance with the nanocomposite.
