Many of us have experienced the distinctive odor of ammonia. Since even 5 ppm of ammonia is clearly odorous, it is necessary to effectively remove ammonia from our living environment and the atmosphere. However, existing common catalysts for ammonia only work at temperatures above 200°C, making it not an energy-saving process. In addition, the high operating temperatures are not suitable for use in familiar living environments. We have reported that gold nanoparticle-supported catalysts and silver atomically dispersed catalysts exhibit high selectivity to N₂ and are capable of oxidation removal even at low temperatures. We are developing catalysts that are energy-efficient and provide clean air.
