Preparation and Characterization of Nano Cu and CuO Catalysts Supported on Washcoated Cordierite

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.
