Abstract

Gas bubbles are ideal hydrophobic structures that underpin technologies ranging from mineral processing to chemical analysis. The technological value of bubbles lies in their ability to create hydrophobic-hydrophilic phase boundaries, simply and efficiently. However, bubbles remain largely incompatible with electrochemical processes: they block charge transfer reactions by interrupting solution-electrode contact. We demonstrate a path to integrate bubbles with electrode reactions. For micrometer-sized electrodes and surface-active reactants (
