For the single step synthesis of dimethyl ether (DME) from synthesis gas a Cu/ZnO/Al2O3-catalyst has been prepared using flame-spray pyrolysis. The resulting powder was co-mixed with -alumina to give an admixed system for DME production. The flame-made catalyst was analyzed using the BET method, in situ XRD, N2O decomposition, TPR and XPS. These studies unraveled that the catalyst exhibited a high Cu surface area including good contact with zinc oxide and alumina as well as small Cu particles resulting in high catalytic activity and product selectivity, also in comparison to a commercially available catalyst.
