Less Bubble Formation on Electrodes for Water-Splitting

摘要

Using electricity to split water into hydrogen and oxygen can be an effective way to produce clean-burning hydrogen fuel.However,the efficiency of water-splitting technologies,often using porous electrode materials with greater surface areas,is often limited by the formation of bubbles that can block or clog the reactive surfaces.A study at the Massachusetts Institute of Technology(MIT;Cambridge,USA)has shown that there are three different ways how bubbles can form on and depart from the surfaces of these porous electrodes.
