The present invention relates to an ammonia production apparatus provided with an ammonia synthesis unit for synthesizing ammonia by a chemical reaction using hydrogen and nitrogen as starting material gases in a reactor and a heat storage unit equipped with a heat medium, the ammonia production ...
Synthesizing ammonia using lower temperatures and pressures could therefore improve its prospects as a chemical means to store and transport energy. Here we report that alkali and alkaline earth metal imides function as nitrogen carriers that mediate ammonia production via a two-step chemical looping ...
selectivity (typically, Faradaic efficiency <1%) for NH3production26,27,28,29,30,31. Therefore, major improvement in N2RR catalysts is essential for the development of low-temperature NH3electrolyzers, which necessitates a better understanding and control of the catalytic materials and the reaction k...

Industrially, the artificial fixation of atmospheric nitrogen to ammonia is carried out using the Haber-Bosch process, but this process requires high temperatures and pressures, and consumes more than 1% of the world's power production. Therefore the search is on for a more environmentally benign ...
Both reaction steps proceed at 1 bar, without added catalysts, and bypass the energy-intensive production of hydrogen, resulting in significant fuel and cost savings. Furthermore, the endothermic reduction step could be carried out using concentrated solar energy as the source of high-temperature ...

Ammonia Chemical Properties,Uses,Production Description Ammonia (chemical formula: NH3) is a compound of nitrogen and hydrogen. As a colorless pungent gas, it is highly soluble in water to become the liquid ammonia. It is also one of the most abundant nitrogen-containing compound in the atmospher...
Alternative routes to the Haber–Bosch process are being sought to electrify ammonia synthesis. Nitric oxide can be electrocatalytically converted into ammonia, but the Faradaic efficiencies and rates of production are currently far below those needed fo
where more than 90% FE of NH3and higher production rates can be achieved under the studied potential window (Supplementary Fig.29). Other possible minor products such as N2and H2were further quantified by gas chromatography, with FEs less than 1%. In fact, gas bubbles could hardly be observed...
