Surface Microbubbles Attenuate Gas-Evolution Reaction at Soft Interfaces
bubble-free regions. Spatial mapping shows that surface bubbles attenuate reactivity beneath them by approximately 2-fold due to restricted access of the alkaline phase. Meanwhile, diffusion-limited bubble growth induces local convective flows that enhance transport of the alkaline phase and dissolved products. The kinetics of thickness change and bubble growth can be tuned by varying the LOHC loading, providing a chemically driven platform for quantitative investigation of gas-evolution reactions.
