In-situ generation and stabilization of gas bubbles for multiphase catalysis.

Introducing stable gas bubbles in liquid is important for the industrial synthesis of chemicals and intermediates via multiphase reactions because of limited solubility of gaseous reactants such as H and O. Herein, a bubble-stabilized system is constructed via in-situ nucleation of bubbles at the surfaces of various polymer nanofibers that circumvents the repulsive interactions between gas-liquid interfaces and nanofibers. During bubble growth processes, nanofibers are self-assembled and interwoven to build spatial nanofiber network surrounding bubbles, firmly trapping bubbles in the liquid phase.
