Researchers engineer light-activated ammonia-to-hydrogen catalyst
A team led by Rice University has designed a method of cracking ammonia that could replace the use of expensive metals for thermocatalysts
A light-activated catalyst made using copper and iron has been used to produce gram-scale quantities of hydrogen gas from ammonia, according to a recently published paper in peer-reviewed journal Science. The researchers say the discovery could pave the way for the replacement of precious metals in catalysts used to reconvert ammonia back to hydrogen. Ammonia has been suggested as a way to safely store and transport hydrogen using existing infrastructure. However, the process of converting hydrogen to ammonia and cracking it back again for end-use can result in energy loss of up to 22pc. Cracking to hydrogen is also an energy-intensive process, requiring high temperatures to speed up reacti
