Mass production of 2D materials by intermediate-assisted grinding ...

Typically, when 2 g of bulk h-BN was used, the production rate of 2D h-BN could reach 0.3 g h −1, which is around 10 times that of a typical ball milling method for preparing amino-functionalized small 2D h-BN sheets . This rate is the highest value reported for h-BN production to date (Supplementary Table S1).
