Abstract:High-efficiency electrocatalytic water splitting requires
high
intrinsic activity of catalysts and even more importantly favorable
mass transfer. However, gas bubbles adhering to the surface of catalysts
limit the re-expose of catalytic active sites to the electrolyte and
reduce the catalytic activities. The efficient desorption of bubbles
can be facilitated by a hierarchical multiscale structure of the electrode
surface. Herein, we report an opened periodic three-dimensional electrode
composed of iron (Fe)-co… Show more
