The Preparation of Palladium -Based Catalyst via Dielectric - Barrier Discharge (DBD) for Total Oxidation of n-butanol and CO at Low Temperature
In the present study, the total oxidation of n-butanol and carbon monoxide (CO) was investigated on 1 wt% Pd/(-Al2O3 catalysts which were prepared via the dielectric-barrier discharge (DBD) and wet-impregnation (WI) methods. All catalysts were characterized by X-ray diffraction (XRD), transmission e...
