Summary: The research team has efficiently converted nitrate, a common pollutant in wastewater and groundwater, into valuable ammonia products using a Ru-dispersed Cu nanowire catalyst through electrochemical methods. This sustainable approach not only treats wastewater but also generates ammonia, but current low catalytic activities pose challenges. However, the team has developed a high-performance catalyst that achieves over 99% nitrate conversion into ammonia and successfully obtains high purity NH4Cl solid and NH3 liquid products.
