Could a new electrode design help make one of the world’s most important chemicals more sustainably?
Researchers from Monash University and RMIT University have developed a new type of lithium-alloying electrode that overcomes a fundamental energy limitation in electrochemical ammonia production.
Ammonia is essential to global agriculture, particularly for nitrogen fertilisers, and is increasingly being explored as a carbon-free fuel and energy carrier. But conventional ammonia production remains heavily dependent on fossil fuels and large, centralised facilities.
The new research, published in Cell Press Blue, shows that changing the chemistry of the cathode can allow the lithium-mediated reaction to operate at substantially more favourable electrical potentials.
Under optimised conditions, the researchers achieved a faradaic efficiency of 96 ± 6%, meaning almost all the electrical current was directed towards producing ammonia.
Lead author Dr Rebecca Hodgetts said the new materials “change the rules of the game” for green ammonia research.
The study also involved Monash University School of Chemistry researchers Emeritus Professor Douglas MacFarlane and Professor Alexandr Simonov.
The team is now working to scale up the cathodes and integrate them into practical electrolyser prototypes, while the technology is being further developed through ongoing research with Monash spin-out Jupiter Ionics Pty Ltd.
