Use of nitrogen, more economical
Nitrogen gas is very abundant in the atmosphere. The industrial use of this nitrogen in the manufacture of plastics, fertilizers, medicines, etc. It is expensive, as it requires a lot of energy to separate nitrogen atoms in gaseous state. In fact, the two atoms that form the nitrogen molecule have a triple bond, and normally the molecules have a single bond or two links between them. A group of the University of Cornell has obtained from the gaseous nitrogen a compound similar to hydrazine, using as catalyst the metal hafnio. The most difficult job is to break the nitrogen bonds, it does the fnio, without an excessive use of energy.
