Hexagonal boron nitride (h‐BN) nanosheets are prepared by a novel and effective method, in which sodium hydroxide and potassium hydroxide molten salts are used to exfoliate h‐BN to obtain nanosheets. BN nanoscrolls are also obtained. The as‐prepared products can be readily dispersed in a wide range of solvents, including water and ethanol, and form stable dispersions.
