Creatine as the nitrogen‐rich, green and cheap compound is used for modification of natural bentonite and the resulting material is employed for the stabilization of Palladium nanoparticles having an average diameter of 3 nm. This new material bento‐crt@Pd is characterized using different techniques such as X‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FTIR), solid state UV‐vis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and energy‐dispersive X‐ray spectroscopy (EDX). This green catalyst promotes efficient reduction of aromatic nitro compounds in aqueous media. By using this catalyst nitroarenes having electron donating as well as electron withdrawing groups were reduced efficiently to their corresponding amines at room temperature. The catalyst can be recycled seven times and the reused catalyst was characterized by TEM and XPS.
