Catalytic transfer hydrogenation of aromatic nitro compounds in presence of polymer-supported nano-amorphous Ni–B catalyst

Polymer-supported nano-amorphous Ni–B particles prepared by ion-exchange-chemical reduction method exhibited good activity in the catalytic transfer hydrogenation of aromatic nitro compounds with hydrazine hydrate as hydrogen donor. The catalyst was characterized by ICP, SEM, TEM, XRD and XPS. The reusability experiments showed that the catalyst was stable and could be used three times with no decrease in activity.
