Utilizing SO2 as self-installing gate to regulate the separation properties of porous graphenes
10.1016/j.carbon.2018.04.004 2018-04-03 We theoretically verify the reversible decoration of the pores of two-dimensional membranes to achieve tailorable separation. We show that SO2 molecules can be used as “self-installing”doors to dynamically adjust the pore size of porous graphene sheets. For H... |
