2D Oxide Nanosheets as a Graphene Analogue with Versatile Functionalities(2)

2014中国国际石墨烯创新大会(Grap-China 2014)——We have produced a variety of 2D nanosheets by exfoliating layered transition metal oxides into colloidal single layers.Osmotic swelling induced by reaction with aqueous amine solutions to homogeneously prop the interlayer gallery up to a hundred times is a key step for high-yield production of unilamellar nanosheets.The resulting 2D oxide crystals have a molecularly thin morphology, which is similar to graphene. On the other hand, these nanosheets are characterized by their rich varieties in composition and structure, which leads to a range of functionalities.
