Au was loaded (1wt.%) on different commercial oxide supports (CuO, Fe2O3, La2O3, MgO, NiO, Y2O3) by a double impregnation method (DIM). Samples were characterised by N2 adsorption at −196°C, scanning electron microscopy, high-resolution transmission electron microscopy, selected area electron diffraction, energy dispersive X-ray spectrometry, high-angle annular dark-field imaging (Z-contrast), X-ray...
The Ce–Zr mixed oxides have been examined as supports for platinum and gold in oxidation of ethanol and toluene. A weight ratio of Ce/Zr in the synthesized supports was 1/1. Two supported noble metals with a different loading (2.5 and 0.3wt.%) were compared to each other as well as to selected industrial catalysts (HHC-5557 and VOC-1544). Whatever the metal content was, Pt catalysts were always more...
