Sheets by wet ball-milling. The 2D MOF nanosheets obtained by topdown methods are usually thinner and with more ex-posed active sites. Howeverthe sies and thicknesses of the nanosheets cannotbeprecisely controlled by this method while the thermally treated nanosheets sometimes could be re-stacked.
Considering good quality and high yield ball milling is an ideal approach to prepare graphene 242526.
2019-3-7A planetary ball mill QM-3SP4 Nanjing Nan Da instrument Co. Ltd China was employed to make rGO-Al composite powders. Stainless steel balls and vials were used and the ball-to-powder weight ratio was 151. The rotation speed was set at 200 rpm and argon gas was used to prevent oxidation of Al during milling.
Layered metal-organic frameworks would be a diverse source of crystalline sheets with nanometer thickness for molecular sieving if they could be exfoliated but there is a challenge in retaining the morphological and structural integrity. We report the preparation of 1-nanometer-thick sheets with large lateral area and high crystallinity from layered MOFs.
