Shifting the catalysis regime to ambient temperatures

What is it about?

How to move the catalysis boundary condition is attempted in the present article. Surface changes (a mild oxidation) influences the catalysis in such a manner that it could shift the catalysis towards ambient temperatures to make it a green reaction. There is some energy space available in the adsorption/desorption and activation energy, which could be fine tuned through surface modification.

Why is it important?

Why should a catalyst works exclusively within a set of boundary conditions ? Can't we shifts this conditions towards the desired and less hazardous direction ? Our article is all about that. By changing the surface with little bit positive (cationic) character, nitric oxide dissociation is enhanced around ambient conditions, that too in the presence of plenty of oxygen. If our concept is correct, it could make the ambient deNOx possible and shift any other catalysis towards ambient conditions.
