| Abstract | ||||
| NANO copper and copper oxide supported on Al 2O3 washcoat deposdeposited on cordierite was prepared by mild reduction method using hydrazine hydrate as reducing agent in non-aqueous media. The effect of loading (5 and 10% Cu), calcination temperature 500, 600 and 700 oC on the formed nano CuO was investigated. The preheated samples were characterized by X-Ray diffraction (XRD) and scanning electron microscope (SEM). The results indicated that, 5wt.% (Cu/Al2O3)/cordierite has the less crystallite size and the smallest crystallite size of CuO was observed in case of 5wt.% (CuO/Al2O3)/cordierite calcined at 500oC for 1hr. | ||||
