In particular, in the second step of the reaction, N 2 O can achieve self-reduction, and its energy barrier is 18.8 kcal/mol. However, the activation energy is not high enough to inhibit the reaction and it is much lower than other typical catalysts, which means that Fe@C 2 N can realize the N 2 O reduction process without using CO as a reductant.

Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle ...
