摘要：
The behavior of surface nanobubbles (SNBs) form at the solid/liquid interface is widely found in industrial fields such as electrocatalysis, fluid transport, and mineral flotation, which can affect the efficiency of the processes in these fields. So, it is essential to regulate the process of bubble formation, in which the clarification of their formation and stabilization mechanisms were required. Here, this article described the research methodologies of nanobubbles formed from both experimental and computational perspectives, discussed the regular pattern of nanobubbles formation under gas types, solid interface properties, and liquid phase additives. Since the stability of nanobubbles after formation is not very clear at present, this article integrated the widely accepted stabilization mechanism of contact line pinning to show the current status of this research area. In addition, considering ionic liquids as important chemical solvents, this article provided an overview of the research on micro-nano bubble formation in ionic-liquid-system. Finally, this review concluded with a prospect of the future, and this article was expected to provide new insights for the study of nanobubbles in ionic-liquid-system. © 2021, Chemical Industry Press Co., Ltd.
