Ferrihydrite Supported on Steel Slags as Catalyst for the Hydrogenation of Nitroarenes: A Virtuous Cycle of Wastes.

ABSTRACT: This study deals with the reduction reaction of nitroarenes using hydrazine monohydrate as the reducing agent and iron-supported steel slag as a novel green heterogeneous catalyst. Steel slag is a byproduct of the steel industry, which, due to its alkalinity, can act as a reactive support that can trigger the formation of catalytically active iron oxides/hydroxides. A systematic study is conducted to evaluate the catalytic activity of steel slags modified with the following salts (or mixtures): FeSO₄·7H₂O, FeCl₃·6H₂O, and FeCl₂·4H₂O. The modified steel slags are characterized by X-ray powder diffraction, Mössbauer spectroscopy, scanning electron microscopy, scanning transmission electron microscopy, energy dispersive X-ray s
