Scientists at Lawrence Livermore National Laboratory (LLNL) are 3D printing graphene aerogel flow-through electrodes (FTEs), core components of electrochemical reactors used for converting CO2 and other molecules to useful products.
Benefiting from the design freedom afforded by 3D printing, the researchers demonstrated they could tailor the flow in FTEs, dramatically improving mass transfer – the transport of liquid or gas reactants through the electrodes and onto the reactive surfaces. The work opens the door to establishing 3D printing as a “viable, versatile rapid-prototyping method” for flow-through electrodes and as a promising pathway to maximizing reactor performance, according to researchers.
