Moving droplets chemically: Vision for tunable electrodes
Abstract
As the world transitions towards new types of energy resources, the importance of large-scale hydrogen production is becoming apparent. Hydrogen production by electrolysis would be a perfect solution in near future, but the efficiency of such a process remains low. One of the main reasons of the low efficiency is the produced bubbles not lifting off the electrode surface on a timely manner, blocking the subsequent production and lowering the efficiency.
In this presentation, I will discuss explored possibilities of improving the aqueous wettability of the electrode surface which will force the bubbles to 'lift off'. Firstly, I will show how a droplet on a surface can be manipulated with specific ions and surfactants. Subsequently, I will discuss how adding an electric field to the chemical driving of droplet might or might not a great solution. I will wrap up by providing an outlook of how the fundamental research of (electro)chemical driving of droplets can lead to efficient and much needed electrodes in future.
