## Description

- description: Developing a mass production method for graphene is essential for practical
    usage of this remarkable material. Direct exfoliation of graphite in liquid is
    the promising approach for production of high quality graphene. However, this
    technique has three huge obstacles to be solved; limitation of solvent, low yield
    and low quaity (i.e., multilayer graphene with small size). Here, we found that
    soluble graphite produced by mechanochemical reaction with salts overcomes the
    above three drawbacks. The soluble graphite was exfoliated into monolayer graphene
    with more than 10 % yield in five minutes of sonication. The modified graphite
    was easily exfoliated in low-boiling point solvent such as acetone, alcohol and
    water without the aid of surfactant. Molecular simulation revealed that the salt
    is adsorbed to the active carbon at the graphite edge. In the case of weak acid
    salts, the original bonding nature between the alkali atom ion and the base molecule
    is kept after the reaction. Thus, the alkali metals are easily dissociated in
    polar solvent, leading to negative charging of graphene, enabling the exfoliation
    of graphite in low boiling point solvents. The approach proposed here opens up
    a new door to practical usage of the attractive 2D material.
