Article Synopsis
  • Gas bubbles form during water electrolysis, where hydrogen and oxygen are generated, and they affect the electrode's performance by decreasing its active area.
  • The study uses grazing incidence small-angle X-ray scattering (GISAXS) and optical microscopy to track how the size and coverage of nanobubbles evolve over time during the electrolysis process.
  • It finds that as more charge is passed, the number of nanobubbles increases while their size decreases, and it suggests that reducing dissolved hydrogen could help minimize nanobubble coverage on the surface.

Recent advances in 3D printing have enabled the manufacture of porous electrodes which cannot be machined using traditional methods. With micron-scale precision, the pore structure of an electrode can now be designed for optimal energy efficiency, and a 3D printed electrode is not limited to a single uniform porosity. As these electrodes scale in size, however, the total number of possible pore designs can be intractable; choosing an appropriate pore distribution manually can be a complex task.

The natural world provides many examples of multiphase transport and reaction processes that have been optimized by evolution. These phenomena take place at multiple length and time scales and typically include gas-liquid-solid interfaces and capillary phenomena in porous media. Many biological and living systems have evolved to optimize fluidic transport.
