AbstractIn this paper molecular dynamics simulations are performed to study the accumulation behaviour of N-2 and H-2 at water/graphite interface under ambient temperature and pressure. It finds that both N-2 and H-2 molecules can accumulate at the interface and form one of two states according to the ratio of gas molecules number to square of graphite surface from our simulation results: gas films (pancake-like) for a larger ratio and nanobubbles for a smaller ratio. In addition, we discuss the stabilities of nanobubbles at different environment temperatures. Surprisingly, it is found that the density of both kinds of gas states can be greatly increased, even comparable with that of the liquid N-2 and liquid H-2. The present results are expected to be helpful for the understanding of the stable existence of gas film (pancake-like) and nanobubbles.
