In situ observation of electrolytic H2 evolution adjacent to gold cathodes

The early stages of gas evolution during electrolytic hydrogen production on Au electrodes are characterized by in situ transmission electron microscopy. The results demonstrate that reaction product molecules initially dissolve into solution and then nucleate near, but not on, the electrodes. The g...

Description
Summary:The early stages of gas evolution during electrolytic hydrogen production on Au electrodes are characterized by in situ transmission electron microscopy. The results demonstrate that reaction product molecules initially dissolve into solution and then nucleate near, but not on, the electrodes. The gas subsequently wets the electrodes and its successive evolution is governed by triple phase boundary line motion.
