Dr. M.N. Shaikh and Prof. Z.H. Yamani of the Center of Research Excellence in Nanotechnology (CENT) have been issued a new patent by the US Patent Office on their innovation on a method of hydrogenating a compound having an N-heterocyclic aromatic ring.

The patent for invention number "US10858327" provides a method of reducing an aromatic ring under relatively mild condition using sub-nano particles of a transition metal supported on super paramagnetic iron oxide nanoparticles (SPIONs). The catalyst is efficient for catalyzing the reduction of both carbocyclic and heterocyclic compound. In compound comprising both carbocyclic and heterocyclic aromatic rings, the catalyst displays high regioselectivity for the heterocyclic ring.
