NH3 is one of the most important chemicals in today's world, as it is used in the production of fertilizers to boost agricultural yields and sustain the ever-growing global population. For over 100 ...

The novel iron-based catalyst exhibits superior performance for ammonia (NH3) synthesis compared to a well-established, century-old counterpart. By designing this new catalyst with an inverse ...

A novel iron-based catalyst with an inverse structure significantly outperforms traditional catalysts in ammonia production, enhancing industrial efficiency.

After World War I, the Provisional Laboratory of Nitrogen was established to develop ammonia and nitric acid synthesis technology. The developed ammonia synthesiscatalyst increased ammonia production ...

The current ammonia synthesis method is the Haber-Bosch process, which involves reacting atmospheric nitrogen and hydrogen produced from methane using an Iron-based catalyst. More than a century after ...

Stage three The pressurised gases are pumped into a tank containing beds of iron catalyst at about 450°C. In these conditions, some of the hydrogen and nitrogen will react to form ammonia.

but characterization of the catalyst and optimization of properties can be more difficult. Large-scale ammonia synthesis is crucial in modern society. Here, the authors present first principles ...
