 Abstract iron making is the largest contributor to global warming, accounting for approximately 7% of all carbon dioxide emissions worldwide. To reduce its environmental impact, researchers have been exploring ways to replace traditional fossil fuel-based reductants with renewable sources such as hydrogen. In this paper, the authors propose a new method of producing iron using ammonia as a reductant, which could potentially revolutionize the iron industry by providing a more efficient and environmentally friendly alternative to current methods.
