In this research, green catalytic iron/copper nanoparticles loaded on bentonite were prepared by the green method using eucalyptus leaves extract as a reducing and capping agent (E-Fe/Cu@B-NPs). The characterization methods were employed on E-Fe/Cu@B-NPs, the NPs results were porous with a spherical shape when analysed by scanning electron microscopy (SEM), the BET analysis showed that the surface...
